draw()

void CeresEngine::UIMenuBar::draw ( UIGraphicsContext &  context, const UIRect &  dirtyRect  )

overridevirtual

Overridden by subclasses to draw the view's texture within the specified rectangle.

Use this method to draw the specified portion of your view's content. Your implementation of this method should be as fast as possible and do as little work as possible. The dirtyRect parameter helps you achieve better performance by specifying the portion of the view that needs to be drawn. You should always limit drawing to the content inside this rectangle. For even better performance, you can call the getRectsBeingDrawn() method and use the list of rectangles returned by that method to limit drawing even further. You can also use the needsToDraw() method test whether objects in a particular rectangle need to be drawn.

The default implementation does nothing. Subclasses should override this method if they do custom drawing. Prior to calling this method, the framework creates an appropriate drawing context and configures it for drawing to the view; you do not need to configure the drawing context yourself.

If your custom view is a direct UIView subclass, you do not need to call super. For all other views, call super at some point in your implementation so that the parent class can perform any additional drawing.

Note

If the view's isOpaque property is true, the view must completely fill the dirtyRect rectangle with opaque content.

Parameters

dirtyRect

A rectangle defining the portion of the view that requires redrawing. This rectangle usually represents the portion of the view that requires updating. When responsive scrolling is enabled, this rectangle can also represent a nonvisible portion of the view that frameworks wants to cache.

getClearsContextBeforeDrawing()

bool CeresEngine::UIMenuBar::getClearsContextBeforeDrawing ( ) const

inlineoverridevirtualnoexcept

A Boolean value that determines whether the view's bounds should be automatically cleared before drawing.

When set to true, the drawing buffer is automatically cleared to transparent black before the draw method is called. This behavior ensures that there are no visual artifacts left over when the view's contents are redrawn. If the view's isOpaque property is also set to true, the getBackgroundColor property of the view will be used when clearing. The default value of this property is true.

If you set the value of this property to false, you are responsible for ensuring the contents of the view are drawn properly in your draw method. If your drawing code is already heavily optimized, setting this property to false can improve performance, especially during scrolling when only a portion of the view might need to be redrawn.

Reimplemented from CeresEngine::UIView.

getIntrinsicContentSize()

UISize CeresEngine::UIMenuBar::getIntrinsicContentSize ( ) const

overridevirtual

The natural size for the receiving view, considering only properties of the view itself.

The default width and height values of this property are set to NSViewNoInstrinsicMetric. For a custom view, you can override this property and use it to communicate what size you would like your view to be based on its content. You might do this in cases where the layout system cannot determine the size of the view based solely on its current constraints. For example, a text field might override this method and return an intrinsic size based on the text it contains. The intrinsic size you supply must be independent of the content frame, because there's no way to dynamically communicate a changed width to the layout system based on a changed height. If your custom view has no intrinsic size for a given dimension, you can set the corresponding dimension to the UIViewNoInstrinsicMetric.

Returns

A size indicating the natural size for the receiving view based on its intrinsic properties.
