bindTemplateCallbackFull

widgetClassBindTemplateCallbackFull

Arguments

:: (HasCallStack, MonadIO m)

=> WidgetClass

widgetClass: A WidgetClass

-> Text

callbackName: The name of the callback as expected in the template XML

-> Callback

callbackSymbol: The callback symbol

-> m ()

Declares a callbackSymbol to handle callbackName from the template XML defined for widgetType. See builderAddCallbackSymbol.

Note that this must be called from a composite widget classes class initializer after calling widgetClassSetTemplate.

Since: 3.10

bindTemplateChildFull

widgetClassBindTemplateChildFull

Arguments

:: (HasCallStack, MonadIO m)

=> WidgetClass

widgetClass: A WidgetClass

-> Text

name: The “id” of the child defined in the template XML

-> Bool

internalChild: Whether the child should be accessible as an “internal-child” when this class is used in GtkBuilder XML

-> Int64

structOffset: The structure offset into the composite widget’s instance public or private structure where the automated child pointer should be set, or 0 to not assign the pointer.

-> m ()

Automatically assign an object declared in the class template XML to be set to a location on a freshly built instance’s private data, or alternatively accessible via widgetGetTemplateChild.

The struct can point either into the public instance, then you should use G_STRUCT_OFFSET(WidgetType, member) for structOffset, or in the private struct, then you should use G_PRIVATE_OFFSET(WidgetType, member).

An explicit strong reference will be held automatically for the duration of your instance’s life cycle, it will be released automatically when ObjectClass.dispose() runs on your instance and if a structOffset that is != 0 is specified, then the automatic location in your instance public or private data will be set to Nothing. You can however access an automated child pointer the first time your classes ObjectClass.dispose() runs, or alternatively in WidgetClass.destroy().

If internalChild is specified, BuildableIface.get_internal_child() will be automatically implemented by the Widget class so there is no need to implement it manually.

The wrapper macros gtk_widget_class_bind_template_child(), gtk_widget_class_bind_template_child_internal(), gtk_widget_class_bind_template_child_private() and gtk_widget_class_bind_template_child_internal_private() might be more convenient to use.

Note that this must be called from a composite widget classes class initializer after calling widgetClassSetTemplate.

Since: 3.10

Arguments

:: (HasCallStack, MonadIO m)

=> WidgetClass

klass: a WidgetClass

-> Text

Arguments

:: (HasCallStack, MonadIO m)

=> WidgetClass

klass: a WidgetClass

-> GParamSpec

pspec: the ParamSpec for the property

=> WidgetClass

widgetClass: class to set the accessible role for

-> Role

role: The role to use for accessibles created for widgetClass

-> m ()

Sets the default Role to be set on accessibles created for widgets of widgetClass. Accessibles may decide to not honor this setting if their role reporting is more refined. Calls to widgetClassSetAccessibleType will reset this value.

In cases where you want more fine-grained control over the role of accessibles created for widgetClass, you should provide your own accessible type and use widgetClassSetAccessibleType instead.

If role is ATK_ROLE_INVALID, the default role will not be changed and the accessible’s default role will be used instead.

Arguments

:: (HasCallStack, MonadIO m)

=> WidgetClass

widgetClass: A WidgetClass

-> BuilderConnectFunc

connectFunc: The BuilderConnectFunc to use when connecting signals in the class template

-> m ()

adjustSizeAllocation

Convert an initial size allocation assigned by a Container using widgetSizeAllocate, into an actual size allocation to be used by the widget. adjust_size_allocation adjusts to a child widget’s actual allocation from what a parent container computed for the child. The adjusted allocation must be entirely within the original allocation. In any custom implementation, chain up to the default Widget implementation of this method, which applies the margin and alignment properties of Widget. Chain up before performing your own adjustments so your own adjustments remove more allocation after the Widget base class has already removed margin and alignment. The natural size passed in should be adjusted in the same way as the allocated size, which allows adjustments to perform alignments or other changes based on natural size.

clearWidgetClassAdjustSizeAllocation :: MonadIO m => WidgetClass -> m ()

adjustSizeRequest

Convert an initial size request from a widget's SizeRequestMode virtual method implementations into a size request to be used by parent containers in laying out the widget. adjust_size_request adjusts from a child widget's original request to what a parent container should use for layout. The forSize argument will be -1 if the request should not be for a particular size in the opposing orientation, i.e. if the request is not height-for-width or width-for-height. If forSize is greater than -1, it is the proposed allocation in the opposing orientation that we need the request for. Implementations of adjust_size_request should chain up to the default implementation, which applies Widget’s margin properties and imposes any values from widgetSetSizeRequest. Chaining up should be last, after your subclass adjusts the request, so Widget can apply constraints and add the margin properly.

set widgetClass [ #getPreferredHeightForWidth := value ]

getPreferredWidth

This is called by containers to obtain the minimum and natural width of a widget. A widget will never be allocated a width less than its minimum and will only ever be allocated a width greater than the natural width once all of the said widget’s siblings have received their natural widths. Furthermore, a widget will only ever be allocated a width greater than its natural width if it was configured to receive extra expand space from its parent container.

clearWidgetClassGetPreferredWidth :: MonadIO m => WidgetClass -> m ()

Set the value of the “get_preferred_width” field to Nothing. When overloading is enabled, this is equivalent to

clear #getPreferredWidth

getPreferredWidthForHeight

This is analogous to WidgetClass.get_preferred_height_for_width() except that it operates in the oposite orientation.

clearWidgetClassGetPreferredWidthForHeight :: MonadIO m => WidgetClass -> m ()

Set the value of the “get_preferred_width_for_height” field to Nothing. When overloading is enabled, this is equivalent to

clear #getPreferredWidthForHeight

setWidgetClassGetPreferredWidthForHeight :: MonadIO m => WidgetClass -> FunPtr C_WidgetClassGetPreferredWidthForHeightFieldCallback -> m ()

Set the value of the “get_preferred_width_for_height” field. When overloading is enabled, this is equivalent to

set widgetClass [ #getPreferredWidthForHeight := value ]

getRequestMode

This allows a widget to tell its parent container whether it prefers to be allocated in SizeRequestModeHeightForWidth or SizeRequestModeWidthForHeight mode. SizeRequestModeHeightForWidth means the widget prefers to have WidgetClass.get_preferred_width() called and then WidgetClass.get_preferred_height_for_width(). SizeRequestModeConstantSize disables any height-for-width or width-for-height geometry management for a said widget and is the default return. It’s important to note (as described below) that any widget which trades height-for-width or width-for-height must respond properly to both of the virtual methods WidgetClass.get_preferred_height_for_width() and WidgetClass.get_preferred_width_for_height() since it might be queried in either SizeRequestMode by its parent container.
