Base class of all UI objects. More...

Detailed Description

Base class of all UI objects.

A class that describes the minimum unit that can be placed in a container (including a window) that takes up some space on the screen, responds to changes in size, position, moving the cursor, pressing / releasing keys and buttons, mouse wheel, etc...

Analogue to Qt's QWidget, Android's View.

Examples: /github/workspace/aui.views/src/AUI/View/AView.h.

◆ invalidateAllStyles()

void AView::invalidateAllStyles ( )

virtual

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 in AAbstractLabel, ATextBase< WordWrappingEngine >, ATextBase< AWordWrappingEngine<> >, and AViewContainerBase.

void AView::invalidateAssHelper ( )

virtual

Resets mAssHelper.

Reimplemented in AViewContainerBase.

◆ invalidateStateStyles()

void AView::invalidateStateStyles ( )

inline

Updates state selectors for ASS.

Unlike invalidateAllStyles, iterates on an already calculated small set of rules which is much more cheap that invalidateAllStyles.

Prefer invalidateStateStyles over invalidateAllStyles when:

Changed state (hover, active, focus) of this view

◆ markPixelDataInvalid()

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

protectedvirtual

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

Parameters

Returns: A window that manages this invalidation event.

Reimplemented in AWindowBase, and AViewContainerBase.

◆ onClickPrevented()

void AView::onClickPrevented ( )

virtual

Called on AWindowBase::preventClickOnPointerRelease.

Reimplemented in ASplitter, and AViewContainerBase.

◆ onGesture()

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

virtual

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 in AWindowBase, AScrollArea, and AViewContainerBase.

◆ onPointerMove()

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

virtual

Handles pointer hover events.

Parameters

pos	event position

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 in AWindow, AWindowBase, A2FingerTransformArea, ADragNDropView, AGridSplitter, ARulerArea, AScrollbarHandle, ASlider, ASplitter, ATreeView::ItemView, and AViewContainerBase.

◆ onPointerPressed()

void AView::onPointerPressed ( const APointerPressedEvent & event )

virtual

Called on pointer (mouse) released event.

Parameters

event event

Reimplemented in ACustomWindow, AWindowBase, A2FingerTransformArea, ADragArea::ADraggableHandle, AGridSplitter, AListItem, AScrollArea, AScrollbarHandle, AScrollbar, ASlider, ASplitter, ATreeView::ItemView, and AViewContainerBase.

◆ onPointerReleased()

void AView::onPointerReleased ( const APointerReleasedEvent & event )

virtual

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.

Reimplemented in ACustomWindow, AWindowBase, A2FingerTransformArea, ADragArea::ADraggableHandle, ADropdownList, AGridSplitter, ARadioButton, AScrollArea, AScrollbarHandle, ASlider, ASplitter, and AViewContainerBase.

◆ onScroll()

void AView::onScroll ( const AScrollEvent & event )

virtual

Handles mouse wheel events.

Parameters

pos	mouse cursor position.
delta	the distance mouse wheel scrolled.

By default, 120 is single mouse wheel click. 120 = mouse scroll down, -120 = mouse scroll up.

Reimplemented in AWindowBase, AScrollArea, AScrollbar, ATreeView, and AViewContainerBase.

◆ onViewGraphSubtreeChanged()

void AView::onViewGraphSubtreeChanged ( )

protectedvirtual

Called when direct or indirect parent has changed.

The method is mostly intended to invalidate styles in order to respond to stylesheet rules (mExtraStylesheet) of the new (in)direct parent.

Emits viewGraphSubtreeChanged signal.

Reimplemented in AViewContainerBase.

◆ postRender()

void AView::postRender ( ARenderContext ctx )

virtual

Performs post-draw routines of this AView. Noone should call this function except rendering routine.

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 in AWindowBase, AAbstractLabel, ACircleProgressBar, ADrawableView, ADropdownList, AProgressBar, ATextBase< WordWrappingEngine >, ATextBase< AWordWrappingEngine<> >, AViewContainerBase, ARulerArea, ARulerView, and ASpinner.

Member Data Documentation

◆ focusState

emits<bool> AView::focusState

Focus state changed.

Parameters

first whether focused or not.

◆ mAssNames

AVector<AString> AView::mAssNames

protected

ASS class names.

Needs keeping order.

◆ mExpanding

glm::ivec2 AView::mExpanding = {0, 0}

protected

Expansion coefficient. Hints layout manager how much this AView should be extended relative to other AViews in the same container.

It does affect expanding environment inside the container. See expanding layout managers for more info.

It does not affect parent's size or parent's expanding property. Use AView::setExpanding() on parent, or ::Expanding variant of declarative container notation (Vertical::Expanding, Horizontal::Expanding, Stacked::Expanding) for such case.

◆ mRedrawRequested

bool AView::mRedrawRequested = false

protected

Redraw requested flag for this particular view/.

This flag is set in redraw() method and reset in AView::render(ARenderContext context). redraw() method does not actually requests redraw of window if mRedrawRequested. This approach ignores sequential redraw() calls if the view is not even drawn.

◆ mSkipUntilLayoutUpdate

bool AView::mSkipUntilLayoutUpdate = true

protected

If set to true, AViewContainer is obligated ignore this view. This value is set to false by AView::setGeometry.

This flag addresses the issue when some container is filled with views by addView during several frames, causing to draw them in wrong place (then their layout is not processed yet).

◆ viewGraphSubtreeChanged

emits AView::viewGraphSubtreeChanged
