uicomponent:ResizeTextResizingComponentToInitialSize(number width, number height)

Many uicomponents are set to resize based on the text they are displaying. Despite this, it is sometimes desireable to resize these uicomponents (to set a different width for a text box that can grow, for example). However, any attempt by script to resize these uicomponents will be overriden by the text resizing behaviour.
This function provides a method of working around this, temporarily disabling the text-resizing behaviour so that the desired resize can be applied.

`DOCK_POINT_TL`	1
`DOCK_POINT_TC`	2
`DOCK_POINT_TR`	3
`DOCK_POINT_CL`	4
`DOCK_POINT_C`	5
`DOCK_POINT_CR`	6
`DOCK_POINT_BL`	7
`DOCK_POINT_BC`	8
`DOCK_POINT_BR`	9

uicomponent:DockingPoint()

Searching and Hierarchy

uicomponent:Find(variable identifier, [boolean assert on fail])

Finds and returns a child of this uicomponent by string name or by numeric index. If a numeric index is supplied, the immediate child uicomponent corresponding to this number is returned. If a string name is supplied, a recursive search is made through all children/descendants of this uicomponent. The first that is found with a matching name is returned.
If the search target was not found then nil is returned. If it was found then it is returned as a component address, which must be cast to a uicomponent script object using the UIComponent function. The find_uicomponent function provided by the script libraries does this automatically, so it's recommended to use that function in place of this function.

Parameters:

variable

Search target, identified by index number or string name.

uicomponent:SequentialFind(... identifiers)

optional, default value=true

Assert if no matching uicomponent could be found.

Returns:

nil

Example - Find a descendent of uic_parent with the name child_a:


								local uic_child_a = uic_parent:Find("child_a")

								if uic_child_a then

								    uic_child_a = UIComponent(uic_child_a)

								end

Example - Perform an operation on each immediate child of uic_parent:


								for i = 0, uic_parent:ChildCount() - 1 do

								    local uic_child = UIComponent(uic_parent:Find(i))

								    -- do stuff

								end

Finds and returns a child of this uicomponent by a series of string names and numeric indexes. The function will step through each argument, attempting to find the uicomponent specified, and using that as the parent from which to find the next. A numeric index argument finds an immediate child of the current search subject, whereas a string name initiates a recursive search through all children/descendants of this uicomponent.
The returned component pointer must be cast to be a usable uicomponent script object using the UIComponent function before it can be used.

Parameters:

...

One or more search targets in a sequence. Each search target should be an index number or string name.

Returns:

address of found component

uicomponent:FindByScriptTag(string script tag unique id that has been specified in the layout)

Finds a component that has been tagged in a layout with the ScriptTag callback using the value of the Context Function id as the unique id to match against. It is a more robust mechanism of searching that sequential find as it is independant from layout order so is less likely to break from layout changes.
The returned component pointer must be cast to be a usable uicomponent script object using the UIComponent function before it can be used.

Parameters:

script tag unique id that has been specified in the layout

Returns:

address of found component

Example:


								uic = UIComponent(root:FindByScriptTag("example_tag"))

uicomponent:FindByGuid(string guid)

Finds a component via its guid (globally unique identifier). A 16 digit hex code that is guranteed to be unique across the game.
The returned component pointer must be cast to be a usable uicomponent script object using the UIComponent function before it can be used.

Parameters:

uicomponent:ChildCount()

GUID that has been specified in the layout

Returns:

address of found component

Example:


								uic = UIComponent(root:FindByGuid("730A2C75-2C65-4337-BCB8189F0C65FAC2"))

Returns the number of immediate children this uicomponent has. These children can be individually retrieved by using uicomponent:Find and supplying a numeric value.

Returns:

number number of children

uicomponent:Parent()

Returns a link to the parent of the uicomponent. This is provided as a component address that must be cast to be a usable uicomponent script object using the UIComponent function.

Returns:

address parent address

Example:


								uic_parent = UIComponent(uic_child:Parent())

uicomponent:Adopt(address uicomponent address, [number insertion index])

Compels this uicomponent to adopt a supplied uicomponent, which will then become a child of this uicomponent. The supplied uicomponent is removed from its previous parent. The target uicomponent must be supplied by its address, which may be retrieved with uicomponent:Address.
An insertion index may optionally be supplied, which determines where in this uicomponent's list of children this new child will be inserted. This can determine the display order in certain circumstances. By default, the new child is added to the end of the list.

Parameters:

address

uicomponent address

uicomponent:Divorce(address child)

optional, default value=-1

insertion index

Returns:

nil

Divorces the supplied child uicomponent from the this uicomponent. The child uicomponent should be supplied by its address, which may be retrieved with uicomponent:Address.
Once divorced, the child uicomponent is not destroyed but goes into an orphan list, from where it may later be adopted by another uicomponent. Orphaned uicomponents are not rendered.

Parameters:

address

child

Returns:

nil

uicomponent:DivorceFromParent()

DivorceFromParent finds the parent (if any) and calls Divorce on it.
Once divorced, the uicomponent is not destroyed but goes into an orphan list, from where it may later be adopted by another uicomponent. Orphaned uicomponents are not rendered.

Returns:

nil

uicomponent:SortChildrenByProperties(... varargs properties)

Reorders the children of the component based on the supplied user properties. Sort by multiple levels if more than one property passed.

Parameters:

...

one or more lua tables in the format {String property_key, bool is_numeric}. Keep in mind that the priority of the properties is in the reverse of the passed order due to lua stack

Returns:

nil

Example - Sort the children of the component first by locked / unlocked state and than by ui_order index:


								child_component:SetProperty("ui_order", "5")

								child_component:SetProperty("locked_first", is_locked and "0" or "1") 

								... create other children and assign the user properties

								component:SortChildrenByProperties({"ui_order", true}--[[secondary--]], {"locked_first", true}--[[primary--]])

Component State Images

To be drawn on a uicomponent, an image has to first be associated with that uicomponent, and then further associated with a state. Only when the uicomponent is set to that state is the image drawn. Once associated with the uicomponent that image can then be associated with multiple states, with its position, colourisation and other parameters customised for each state. The functions in the previous section allow parameters of the image's association with the uicomponent, which would affect each component state that the image is displayed with, to be queried and changed. The parameters of an image's association with a particular state may be changed using the functions in this section.

In the source code, an image's association with the uicomponent is called a ComponentImage, and a ComponentImage's association with a particular state is called a ComponentImageMetrics. The functions described in this section relate to ComponentImageMetrics, therefore.

Priority and Locking

Every component within the UI hierarchy has a non-negative integer priority value associated with it, with a default value of 0. This is used for a handful of things:

Priority is used to sort the immediate children of the root component.

Priority is also used to sort any components set to be topmost with uicomponent:RegisterTopMost.

Priority is mainly used when a priority lock is activated.

Priority locks are activated on a target component, with a numeric lock value. When a priority lock is activated, any component within the whole UI (including the target component) with a priority value less than the priority of the lock becomes inactive and visually desaturated. This method can be used to grey out background buttons and other controls when a foreground panel is active, for example.

Priority values can be set and queried, and priority locks can be activated and deactivated, using the methods in script described below.

uicomponent:LockPriority([number priority])

Activates a priority lock on the uicomponent, replacing any existing lock that's active on this component. This disables all uicomponents with a priority value less than the priority of the lock. A priority may optionally be specified - if not, the uicomponent's own priority is used for the lock value. This will exempt this uicomponent from the lock, which is usually desired.
uicomponent:UnLockPriority must be called after calling this function to restore normal ui functionality.

Parameters:

uicomponent:UnLockPriority()

optional, default value=nil

Lock priority. If no value is specified here then the lock is activated using the component's own priority is used.

Returns:

nil

Deactivates any active priority lock on the uicomponent.

Returns:

nil

uicomponent:PriorityLockInfo()

Returns whether a priority lock is currently active or not in the UI. If a lock is active, the priority value and a pointer to the locked component are also returned. This component pointer must be cast to be a usable uicomponent script object using the UIComponent function before it can be used.

Returns:

boolean is priority locked
number lock value
address component address

Example:


								local active, priority, component = core:get_ui_root():IsPriorityLockActive()

								if active then

								local uic = UIComponent(component)

								out("Priority lock with value [" .. priority .. "] is active on component with id [" .. uic:Id() .. "]")

								else

								out("No priority lock active")

								end

uicomponent:IsPriorityLocked()

Returns whether this component is currently priority locked. This is true if a priority lock is active on any component (including this one) with a level greater than this component's priority, or false otherwise. If this component is priority locked then it will (probably) be disabled and visually desaturated on the display.

Returns:

boolean is priority locked

uicomponent:Priority()

Returns the priority value of this uicomponent.

Returns:

number priority

uicomponent:SetPriority(number priority)

uicomponent:PropagatePriority(number priority)

Sets the component priority of this uicomponent and all its children to the supplied value. The old priority of the uicomponent is returned.

Parameters:

uicomponent:RegisterTopMost()

priority

Returns:

number old priority

Registers this uicomponent to be drawn topmost. Topmost uicomponents are drawn outside of the normal hierarchy on the top of all other uicomponents. This setting is useful for uicomponents such as tooltips that must always be drawn over the top of other visible parts of the UI.

Returns:

nil

uicomponent:RemoveTopMost()

De-registers this uicomponent from being drawn topmost.

Returns:

nil
