The graphical user interface elements are defined within {{path|interface/*.gui}} files, as typical code formatting. The files only decide on the positions of how elements are arranged, [[Scripted GUI modding|scripted GUI]] is used to assign effects to newly-created interface elements. | |||
== | == Overview == | ||
The interface consists of [[#Containers|container windows (or containers)]] and elements within them. Each element, other than containers, must reside in a container. Containers can be nested in other elements to organise their positions. Gridboxes are used to clone the same container several times, with different details specified for each one. Newly-added elements can have their effects defined in [[Scripted GUI modding|scripted GUI]], while the effects of base game's GUI are hard-coded, that is, it's impossible to modify what it does directly. | |||
The elements are shown in the order that they are defined in the file: what's placed later will be shown on top of what's placed earlier. The files are contained within a <code>guiTypes = { ... }</code> block overarching the entire file. | |||

{{anchor|ContainerWindowType}} | |||
Containers are used to group together elements and associate them with an internal function, written as a <code>containerWindowType = { ... }</code> block. | |||
New containers that are independent (not inside of any other container) will not show up in-game by default. For one to show up, it is required for it to be tied to a function, such as [[Scripted GUI modding|scripted GUI]], which decides where it should show and when. In some cases, new containers can be created for the internally-defined functions, such as [[Technology modding#Graphical user interface|new technology folders]] or [[Music modding#Radio stations|getting a music station to show up]]. In most cases, however, a scripted GUI would be required to make a new container show up. | |||
If a container is defined within another container, it will appear at the same time as the window containing it unless more information is defined within the function. A scripted GUI cannot be assigned to such a container, however. In some cases, it's not necessary for a container to be visible to be useful, for example, an empty container can be used as an anchor, that is, used as the [[Scripted GUI modding#Parent Window Token|parent window name]] for Scripted GUI to place another container on the same place as the anchor is defined. This can allow placing containers with higher precision than normally possible with <code>parent_window_name</code>, allowing the parent window to have elements drawn on top of the scripted GUI. | |||
< | |||
=== Arguments === | |||
< | The following attributes are commonly used: | ||
* <code>name = "my_container"</code> – The name of the container, used to tie a function to the container. Independent containers must have unique names. While nested containers may have name overlap when defined in different independent containers, it's still preferable to avoid overlap, such as to ensure unambiguity when using <code>parent_window_name</code> in scripted GUI. | |||
* <code>size = { height = 300 width = 100%% }</code> – The bounding box for the container. If this container is placed inside of another one, either directly or through a gridbox, then only this size is used to create the scrollbar, without taking into account elements inside. This boundary also sets the size that the scrollbar must use. Either in pixels or in percentages relative to the size of the parent container (the entire screen if independent). | |||
* <code>background = { ... }</code> – The background of the container. This is required for a scrollbar to work, as otherwise the boundaries will get ignored. There are the following arguments inside: | |||
** <code>name = "Background"</code> – The name for handling the background in other functions. Commonly just set to "Background". | |||
** <code>spriteType = "GFX_tiled_window"</code> or <code>quadTextureSprite = "GFX_tiled_window_transparent"</code> – Refers to a [[Graphical asset modding#corneredTileSpriteType|corneredTileSpriteType]] definition that would automatically get resized to fit the container's set size. | |||
* <code>clipping = yes</code> – If true (and if a background exists), the elements inside of the container will not be able to go outside of the boundary box, and what doesn't fit will get cropped. Defaults to true. This being true is mandatory for a scrollbar to work. | |||
* <code>position = { x = 100 y = 100 }</code> – The position of the container in pixels relative to the set orientation. | |||
* <code>orientation = center</code> – Sets the origin that the position is measured relative to, such as <code>upper_left</code>, <code>center_down</code>, or <code>lower_right</code>. | |||
* <code>moveable = yes</code> – If set, the container can be moved by the player with their cursor. | |||
* <code>fullScreen = yes</code> – If set, the container will be considered to cover the entire screen. | |||
Animation can be assigned to containers with these attributes: | |||
* <code>show_position = { x = 300 y = 100 }</code> – The screen position where the container will show up to the player after the 'show' animation finishes. | |||
</ | * <code>hide_position = { x = 100 y = 100 }</code> – The screen position the container aims for during the 'hide' animation. | ||
* <code>show_animation_type = linear</code> – The animation type used to show the container (<code>decelerated</code> or <code>linear</code>). | |||
* <code>hide_animation_type = accelerated</code> – The animation type used to hide the container (<code>accelerated</code> or <code>linear</code>). | |||
* <code>animation_type = decelerated</code> – The animation if both show and hide animations are supposed to be the same (<code>accelerated</code>, <code>decelerated</code>, or <code>linear</code>). | |||
* <code>animation_time = 1000</code> – The animation time in milliseconds. | |||
* <code>show_sound = menu_open_window</code> – The [[Sound modding|sound]] to play during the 'show' animation. | |||
* <code>hide_sound = menu_close_window</code> – The [[Sound modding|sound]] to play during the 'hide' animation. | |||
* <code>fade_time = 300</code> – The time it takes for the container to fade in, in milliseconds. | |||
* <code>fade_type = linear</code> – The type of fade in: either <code>accelerated</code> or <code>linear</code>. | |||
== | === Scrolling === | ||
Scrolling can be done via scrollbars. If scrollbars are enabled, it's also possible to enabled it with dragging the screen. Since the game has to know what should be inside of the container, there are some attributes which must be used in the container. <code>size = { ... }</code> has to be defined using pixels instead of percentage values (for directions where scrolling is enabled) to ensure that it doesn't stretch to fit all elements. <code>clipping = yes</code> should be true (or unset, making it default to true). A <code>background = { ... }</code> also has to be defined for the container, since it establishes the boundaries. | |||
Scrollbars use [[#extendedScrollbarType|extendedScrollbarType]] definitions. If this definition is inside of a container, in which case it will be automatically assigned to the container without needing to assign it manually, however it can't be used for any other container. If the definition is entirely independent, it will not be assigned to any by default, but can be re-used in multiple containers. | |||
In particular, these arguments enable scrolling, assuming the conditions are fulfilled: | |||
* <code>verticalScrollbar = scrollbar_name</code> assigns an external ExtendedScrollbarType to act as the vertical scrollbar. The scrollbar can't have <code>horizontal = yes</code> in its definition. | |||
* <code>horizontalScrollbar = scrollbar_name</code> assigns an external ExtendedScrollbarType to act as the horizontal scrollbar. The scrollbar must have <code>horizontal = yes</code> in its definition. | |||
* <code>drag_scroll = { left middle right }</code> enables drag scrolling. The drag scrolling will only work if there exists a scrollbar for the same axis. The direction represent the mouse button that the scrolling can be done with, however only <code>left</code> seems to work in-game. If there's only one button, it can be shortened as <code>drag_scroll = left</code>. | |||
== | In addition, there are optional attributes that can be used to refine the scrollbar: | ||
* <code>margin = { top = 10 bottom = 10 left = 20 right = 20 }</code> is used to determine the margins of the container. These areas will be taken as the border of the window, unaffected by the scrollbar; only what's inside of the margin's border will be modified by the scrollbar. | |||
* <code>autohide_scrollbars = no</code> – By default, a scrollbar will not appear if it isn't necessary due to all elements being inside of the container's <code>size</code>. If this is set to false, then it will always appear. | |||
* <code>scroll_wheel_factor = 40</code> determines how much a single mouse scroll will affect the scrollbar. | |||
* <code>smooth_scrolling = yes</code> enables a smoother scrolling animation. | |||

== | == Position and Orientation == | ||
Understanding how the position coordinates work is important to understanding how to edit interfaces correctly. | |||
The ''orientation'' attribute used by an element (or container) informs you where the anchor point for the element is. For example, ''UPPER_LEFT'' means the ''( 0, 0 )'' position is in the top left corner of the screen/container, whereas ''LOWER_RIGHT'' is the bottom right. | |||
The ''position'' attribute then works from this origin position. Therefore if you want an element to be on the opposite side of the screen, you'd want to change the ''orientation'' first. | |||
This is system is used because it allows the interface to adapt to different resolutions. Because all positions are tied to a specific origin that is dynamically calculated from the player's screen resolution, the placement of containers and elements are kept consistent. | |||
So, if you want to ensure your interface edits are consistent, you must use the ''orientation'' attribute properly. | |||
An mistake would be to edit the ''position'' solely, for example <code>position = { x = 1800 y = 200 }</code>. This would look fine for anybody with a screen width greater than 1800px (i.e. 1900 x 1200 upwards), but the element would be off screen for those with smaller screens. | |||

The graphical user interface elements are defined within /Hearts of Iron IV/interface/*.gui files, as typical code formatting. The files only decide on the positions of how elements are arranged, scripted GUI is used to assign effects to newly-created interface elements.
Overview
The interface consists of container windows (or containers) and elements within them. Each element, other than containers, must reside in a container. Containers can be nested in other elements to organise their positions. Gridboxes are used to clone the same container several times, with different details specified for each one. Newly-added elements can have their effects defined in scripted GUI, while the effects of base game's GUI are hard-coded, that is, it's impossible to modify what it does directly.
The elements are shown in the order that they are defined in the file: what's placed later will be shown on top of what's placed earlier. The files are contained within a guiTypes = { ... }
block overarching the entire file.
Constants
- This section is transcluded from Data structures § Constants
Constants serve as a way to use the same value with a reference. The constants are marked with the @
symbol when defining or using them. An example definition is the following:
@CONSTANT_1 = 10 @CONSTANT_2 = "TAG_my_idea"
This can later be used in the file as, for example, cost = @CONSTANT_1
. These definitions can be in any point of the file.
Constants are available in the vast majority of game files, including most, if not all, *.txt and *.gui files. Constants can be used as a way to link several values to be the same if they can easily be changed at any point in the development. However, constants that store a string for its value can only be used in triggers and the attributes of elements and windows, trying to use them in an effect will result in an "invalid database object for effect/trigger" error.
For example, if there is a large decision system where every decision is intended to have the same cost, then these constants may be used if the political power cost gets changed mid-development for better balance.
Another example would be a scripted GUI container: if a large multitude of elements are to be at the same X or Y position, it might be worth it to link them to be a constant in case their position could be changed for better appearance or to fit in another GUI element.
Example decision file that utilises constants:
@CONSTANT_1 = 10 @CONSTANT_2 = "TAG_my_idea" TAG_decision_category = { TAG_decision = { icon = test_icon cost = @CONSTANT_1 complete_effect = { if = { limit = { has_ideas = @CONSTANT_2 } add_stability = 0.1 } } } }
Containers
Containers are used to group together elements and associate them with an internal function, written as a containerWindowType = { ... }
block.
New containers that are independent (not inside of any other container) will not show up in-game by default. For one to show up, it is required for it to be tied to a function, such as scripted GUI, which decides where it should show and when. In some cases, new containers can be created for the internally-defined functions, such as new technology folders or getting a music station to show up. In most cases, however, a scripted GUI would be required to make a new container show up.
If a container is defined within another container, it will appear at the same time as the window containing it unless more information is defined within the function. A scripted GUI cannot be assigned to such a container, however. In some cases, it's not necessary for a container to be visible to be useful, for example, an empty container can be used as an anchor, that is, used as the parent window name for Scripted GUI to place another container on the same place as the anchor is defined. This can allow placing containers with higher precision than normally possible with parent_window_name
, allowing the parent window to have elements drawn on top of the scripted GUI.
Arguments
The following attributes are commonly used:
name = "my_container"
– The name of the container, used to tie a function to the container. Independent containers must have unique names. While nested containers may have name overlap when defined in different independent containers, it's still preferable to avoid overlap, such as to ensure unambiguity when usingparent_window_name
in scripted GUI.size = { height = 300 width = 100%% }
– The bounding box for the container. If this container is placed inside of another one, either directly or through a gridbox, then only this size is used to create the scrollbar, without taking into account elements inside. This boundary also sets the size that the scrollbar must use. Either in pixels or in percentages relative to the size of the parent container (the entire screen if independent).background = { ... }
– The background of the container. This is required for a scrollbar to work, as otherwise the boundaries will get ignored. There are the following arguments inside:name = "Background"
– The name for handling the background in other functions. Commonly just set to "Background".spriteType = "GFX_tiled_window"
orquadTextureSprite = "GFX_tiled_window_transparent"
– Refers to a corneredTileSpriteType definition that would automatically get resized to fit the container's set size.
clipping = yes
– If true (and if a background exists), the elements inside of the container will not be able to go outside of the boundary box, and what doesn't fit will get cropped. Defaults to true. This being true is mandatory for a scrollbar to work.position = { x = 100 y = 100 }
– The position of the container in pixels relative to the set orientation.orientation = center
– Sets the origin that the position is measured relative to, such asupper_left
,center_down
, orlower_right
.moveable = yes
– If set, the container can be moved by the player with their cursor.fullScreen = yes
– If set, the container will be considered to cover the entire screen.
Animation can be assigned to containers with these attributes:
show_position = { x = 300 y = 100 }
– The screen position where the container will show up to the player after the 'show' animation finishes.hide_position = { x = 100 y = 100 }
– The screen position the container aims for during the 'hide' animation.show_animation_type = linear
– The animation type used to show the container (decelerated
orlinear
).hide_animation_type = accelerated
– The animation type used to hide the container (accelerated
orlinear
).animation_type = decelerated
– The animation if both show and hide animations are supposed to be the same (accelerated
,decelerated
, orlinear
).animation_time = 1000
– The animation time in milliseconds.show_sound = menu_open_window
– The sound to play during the 'show' animation.hide_sound = menu_close_window
– The sound to play during the 'hide' animation.fade_time = 300
– The time it takes for the container to fade in, in milliseconds.fade_type = linear
– The type of fade in: eitheraccelerated
orlinear
.
Scrolling
Scrolling can be done via scrollbars. If scrollbars are enabled, it's also possible to enabled it with dragging the screen. Since the game has to know what should be inside of the container, there are some attributes which must be used in the container. size = { ... }
has to be defined using pixels instead of percentage values (for directions where scrolling is enabled) to ensure that it doesn't stretch to fit all elements. clipping = yes
should be true (or unset, making it default to true). A background = { ... }
also has to be defined for the container, since it establishes the boundaries.
Scrollbars use extendedScrollbarType definitions. If this definition is inside of a container, in which case it will be automatically assigned to the container without needing to assign it manually, however it can't be used for any other container. If the definition is entirely independent, it will not be assigned to any by default, but can be re-used in multiple containers.
In particular, these arguments enable scrolling, assuming the conditions are fulfilled:
verticalScrollbar = scrollbar_name
assigns an external ExtendedScrollbarType to act as the vertical scrollbar. The scrollbar can't havehorizontal = yes
in its definition.horizontalScrollbar = scrollbar_name
assigns an external ExtendedScrollbarType to act as the horizontal scrollbar. The scrollbar must havehorizontal = yes
in its definition.drag_scroll = { left middle right }
enables drag scrolling. The drag scrolling will only work if there exists a scrollbar for the same axis. The direction represent the mouse button that the scrolling can be done with, however onlyleft
seems to work in-game. If there's only one button, it can be shortened asdrag_scroll = left
.
In addition, there are optional attributes that can be used to refine the scrollbar:
margin = { top = 10 bottom = 10 left = 20 right = 20 }
is used to determine the margins of the container. These areas will be taken as the border of the window, unaffected by the scrollbar; only what's inside of the margin's border will be modified by the scrollbar.autohide_scrollbars = no
– By default, a scrollbar will not appear if it isn't necessary due to all elements being inside of the container'ssize
. If this is set to false, then it will always appear.scroll_wheel_factor = 40
determines how much a single mouse scroll will affect the scrollbar.smooth_scrolling = yes
enables a smoother scrolling animation.

Elements
There are multiple element types used within containers. All elements must be used within containers, they will not work outside of one.
Elements will inherit the orientation of the containers they are located in unless the orientation is specified for the element itself.
The following elements can be freely added and are usable with scripted GUIs.
- iconType - Used for static images.

Position and Orientation
Understanding how the position coordinates work is important to understanding how to edit interfaces correctly.
The orientation attribute used by an element (or container) informs you where the anchor point for the element is. For example, UPPER_LEFT means the ( 0, 0 ) position is in the top left corner of the screen/container, whereas LOWER_RIGHT is the bottom right.
The position attribute then works from this origin position. Therefore if you want an element to be on the opposite side of the screen, you'd want to change the orientation first.
This is system is used because it allows the interface to adapt to different resolutions. Because all positions are tied to a specific origin that is dynamically calculated from the player's screen resolution, the placement of containers and elements are kept consistent.
So, if you want to ensure your interface edits are consistent, you must use the orientation attribute properly.
An mistake would be to edit the position solely, for example position = { x = 1800 y = 200 }
. This would look fine for anybody with a screen width greater than 1800px (i.e. 1900 x 1200 upwards), but the element would be off screen for those with smaller screens.
Valid orientation values (can be upper or lowercase):
- CENTER
- UPPER_LEFT
- LOWER_LEFT
- UPPER_RIGHT
- LOWER_RIGHT
