Detailed Description

Member Function Documentation

◆ commitStyle()

void AAbstractLabel::commitStyle ( )

overrideprotectedvirtual

Reimplemented from AView.

◆ consumesClick()

bool AAbstractLabel::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 AButton.

◆ getContentMinimumHeight()

int AAbstractLabel::getContentMinimumHeight ( )

overridevirtual

Returns: minimal content-area height.

Reimplemented from AView.

◆ getContentMinimumWidth()

int AAbstractLabel::getContentMinimumWidth ( )

overridevirtual

Returns: minimal content-area width.

Reimplemented from AView.

Reimplemented in ADropdownList, and APageSwitch.

◆ invalidateAllStyles()

void AAbstractLabel::invalidateAllStyles ( )

overridevirtual

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.

◆ invalidateFont()

void AAbstractLabel::invalidateFont ( )

overridevirtual

Implements IFontView.

◆ onDpiChanged()

void AAbstractLabel::onDpiChanged ( )

overridevirtual

Reimplemented from AView.

◆ render()

void AAbstractLabel::render ( ARenderContext ctx )

overridevirtual

Draws this AView. Noone should call this function except rendering routine.

See also: AView::drawView

AView::render is not guaranteed to be called on per-frame basis. Moreover, this method can be called multiple times if render-to-texture caching decides to do so.

Reimplemented from AView.

Reimplemented in ADropdownList.

◆ setSize()

void AAbstractLabel::setSize ( glm::ivec2 size )

overridevirtual

Reimplemented from AView.

◆ toString()

AString AAbstractLabel::toString ( ) const

overridevirtual

Returns: string representation of the object

Implements IStringable.
