Detailed Description

A view that represents a set of views.

AViewContainerBase can store, render, resize, provide events to and handle the child views.

AViewContainerBase does not control the position and size of the child views by itself; instead, it delegates that responsibility to it's layout manager.

Since AViewContainerBase is an instance of AView, AViewContainerBase can handle AViewContainerBases recursively, thus, making possible complex UI by nested AViewContainerBases with different layout managers.

This class is abstract. The methods for modifying it's views are protected. You can use AViewContainer which exposes these methods to public or extend AViewContainerBase to make your own container-like view.

Examples: /home/runner/work/aui/aui/aui.views/src/AUI/View/AView.h.

Member Function Documentation

◆ addViewCustomLayout()

void AViewContainerBase::addViewCustomLayout ( const _< AView > & view )

protected

Adds view to container without exposing it to the layout manager.

User is obligated to manage view's layout by themselves. Implement applyGeometryToChildren() to do so.

View is not visible until it's layout is determined.

See also: AView::mSkipUntilLayoutUpdate

◆ capturesFocus()

bool AViewContainerBase::capturesFocus ( )

overridevirtual

Returns: Can this view capture focus.

For containers, capturing focus is redundant.

Reimplemented from AView.

◆ consumesClick()

bool AViewContainerBase::consumesClick ( const glm::ivec2 & pos )

overridevirtual

Determines whether this AView processes this click or passes it thru.

Parameters

pos	mouse position

Returns: true if AView processes this click

Used in AViewContainer::getViewAt method subset, thus affecting click event handling.

Reimplemented from AView.

Reimplemented in AWindow.

◆ focusChainTarget()

_< AView > AViewContainerBase::focusChainTarget ( )

inline

Returns: Focus chain target.

See mFocusChainTarget for further info.

◆ forceUpdateLayoutRecursively()

void AViewContainerBase::forceUpdateLayoutRecursively ( )

overridevirtual

Reimplemented from AView.

◆ getContentMinimumHeight()

int AViewContainerBase::getContentMinimumHeight ( )

overridevirtual

Returns: minimal content-area height.

Reimplemented from AView.

Reimplemented in ATreeView::ContainerView.

◆ getContentMinimumWidth()

int AViewContainerBase::getContentMinimumWidth ( )

overridevirtual

Returns: minimal content-area width.

Reimplemented from AView.

Reimplemented in ATreeView::ContainerView.

◆ getViewAt()

_< AView > AViewContainerBase::getViewAt	(	glm::ivec2	pos,
		ABitField< AViewLookupFlags >	flags = AViewLookupFlags::NONE ) const

nodiscardvirtualnoexcept

Finds first direct child view under position.

Parameters

pos	position relative to this container
flags	see AViewLookupFlags

Returns: found view or nullptr

Some containers may implement getViewAt by it's own (i.e. AListView for performance reasons).

Reimplemented in AListViewContainer.

◆ getViewAtRecursive() [1/2]

_< AView > AViewContainerBase::getViewAtRecursive	(	glm::ivec2	pos,
		ABitField< AViewLookupFlags >	flags = AViewLookupFlags::NONE ) const

nodiscardnoexcept

Acts as AViewContainerBase::getViewAt but recursively (may include non-direct child).

Parameters

pos	position relative to this container
flags	see AViewLookupFlags

Returns: found view or nullptr

◆ getViewAtRecursive() [2/2]

template<aui::predicate< _< AView > > Callback>

bool AViewContainerBase::getViewAtRecursive	(	glm::ivec2	pos,
		const Callback &	callback,
		ABitField< AViewLookupFlags >	flags = AViewLookupFlags::NONE )

inline

Acts as AViewContainerBase::getViewAtRecursive but calls a callback instead of returning value.

Parameters

pos	position relative to this container
callback	callback to call
flags	see AViewLookupFlags

Returns: true if callback returned true; false otherwise

The passed callback is a predicate. If predicate returns true, the execution of lookup is stopped and getViewAt returns true. If predicate returns false, the lookup continues.

◆ getViewAtRecursiveOfType()

template<typename T>

_< T > AViewContainerBase::getViewAtRecursiveOfType	(	glm::ivec2	pos,
		ABitField< AViewLookupFlags >	flags = AViewLookupFlags::NONE )

inline

Acts as AViewContainerBase::getViewAtRecursive but finds a view castable to specified template type.

Parameters

pos	position relative to this container
flags	see AViewLookupFlags

Returns: found view or nullptr

◆ invalidateAllStyles()

void AViewContainerBase::invalidateAllStyles ( )

overrideprotectedvirtual

Invalidates all styles, causing to iterate over all rules in global and parent stylesheets.

Unlike invalidateStateStyles(), completely resets styles for this view, causing it to iterate over all rules in global and parent stylesheets. This operation is much more expensive than invalidateStateStyles because invalidateStateStyles iterates over a small set of rules and performs fewer checks.

Prefer invalidateAllStyles over invalidateStateStyles when:

Added/removed rules to applicable stylesheets
The view is reinflated to other layout
Added/removed/changed ass names of this or parent views

Reimplemented from AView.

◆ invalidateAssHelper()

void AViewContainerBase::invalidateAssHelper ( )

overrideprotectedvirtual

Resets mAssHelper.

Reimplemented from AView.

◆ markMinContentSizeInvalid()

void AViewContainerBase::markMinContentSizeInvalid ( )

overridevirtual

Reimplemented from AView.

◆ markPixelDataInvalid()

void AViewContainerBase::markPixelDataInvalid ( ARect< int > invalidArea )

overridevirtual

A view requests to redraw it and passes it's coords relative to this.

Parameters

invalidArea area to invalidate. Must be in this view's coordinate space.

Reimplemented from AView.

Reimplemented in AWindowBase.

◆ onCharEntered()

void AViewContainerBase::onCharEntered ( char16_t c )

overridevirtual

Reimplemented from AView.

◆ onClickPrevented()

void AViewContainerBase::onClickPrevented ( )

overridevirtual

Called on AWindowBase::preventClickOnPointerRelease.

Reimplemented from AView.

◆ onDpiChanged()

void AViewContainerBase::onDpiChanged ( )

overridevirtual

Reimplemented from AView.

◆ onGesture()

bool AViewContainerBase::onGesture	(	const glm::ivec2 &	origin,
		const AGestureEvent &	event )

overridevirtual

Handles touch screen gesture event.

Parameters

origin	position where the event(s) started to occur from.
event	gesture event.

Note: The standard implementation AView::onGesture emulates desktop events such as right click and scroll.

See also: transformGestureEventsToDesktop

Returns: true, if consumed (handled). True value prevents click.

Reimplemented from AView.

Reimplemented in AWindowBase.

◆ onKeyDown()

void AViewContainerBase::onKeyDown ( AInput::Key key )

overridevirtual

Reimplemented from AView.

void AViewContainerBase::onPointerMove	(	glm::vec2	pos,
		const APointerMoveEvent &	event )

overridevirtual

Handles pointer hover events.

Parameters

pos	event position
event	event description

Note: If the view is pressed, it would still received move events. Use AView::isMouseHover to check is the pointer actually over view or not. See AView::onPointerReleased for more info.

Reimplemented from AView.

Reimplemented in ATreeView::ItemView, AWindow, and AWindowBase.

◆ onPointerPressed()

void AViewContainerBase::onPointerPressed ( const APointerPressedEvent & event )

overridevirtual

Called on pointer (mouse) released event.

Parameters

event event

Reimplemented from AView.

Reimplemented in ATreeView::ItemView, and AWindowBase.

◆ onPointerReleased()

void AViewContainerBase::onPointerReleased ( const APointerReleasedEvent & event )

overridevirtual

Called on pointer (mouse) released event.

Parameters

event event

Note: To handle clicks, you should use AView::clicked signal instead. View still receives pointer move and released events even if cursor goes outside the view boundaries, or other exclusive event appeared (i.e. scrollarea scroll). AView::clicked emitted only if release event occurred inside view and no other event has prevented click gesture. See APointerReleasedEvent::triggerClick.
