3.7.3 Context Menus

To add a context menu to your morph class, the first thing to do is take over mouse handling:

	handlesMouseDown: anEvent 
		^ true. 

Next, decide if you want to start with the standard menu, or go totally custom. If you want to include the standard options, compile:

	defaultYellowButtonMenuEnabled 
		^ true. 

Then create #addCustomMenuItems:hand: with your morph-specific items. Here's an excerpt from TextMorph:

	addCustomMenuItems: aCustomMenu hand: aHandMorph
		super addCustomMenuItems: aCustomMenu hand: aHandMorph.
		aCustomMenu add: 'text margins...' translated action: #changeMargins:.

If you'd rather take full control and start from scratch, build your menu in #addYellowButtonMenuItemsTo:event:. Here's an excerpt from Morph's default menu:

	addYellowButtonMenuItemsTo: aMenu event: evt 
		aMenu defaultTarget: self.
		"snipped..."
		aMenu addStayUpItem.
		self cmdGesturesEnabled ifTrue: [
			aMenu addLine.
			aMenu add: 'inspect' translated action: #inspect].
