This is complex stuff! What I need is detailed instructions to build your exact setup. I guess it involves updated Cuis, and DrGeo. If those instructions are in the readme of DrGeo repo, that's even better. Then, I'll need to play a bit with this and review the code. My gut feeling is that DropDownListMorph should not have any modal-specific code. That should be in the base framework. Having a concrete example to experiment with will help me find out the best way to do it. Thanks!

I fixed the issue by borrowing the code from popup menu (it is modal behavior). So to pop up my drop down list of morph, I have this method: <pre>PluggableDropDownListOfMorph>>popUpAt: position forHand: hand in: aWorld aWorld addMorphFront: self position: position. self fitInWorld. prevKbdFocus _ hand keyboardFocus. prevMouseFocus _ hand mouseFocus. hand newMouseFocus: self; newKeyboardFocus: self </pre> The modal behavior is perfectly achieved. However, the scroll morph in the list morph does not receive event anymore (but it is part of the . Observe on the screenshot below, the scrollbar is not highlight how it should be: <img moz-do-not-send="false" src="cid:part1.00080002.01010206@zoho.com" alt="" height="217" width="202"> When I click on the scroll bar, the event is directed to the list of morphs (colored boxes), of course it produces an error as it does not match with any morph of the list (colored boxes). So I edit a bit the method below to handle the mouse up button event. Now It makes the scrollbar slider and buttons inoperable by the user, only it can be controlled with the mouse scrolling wheel button. The related mouse button up event is handled as: <pre>mouseButton1Up: aMouseButtonEvent localPosition: localEventPosition "Handle a mouse up event." (self includesPixel: aMouseButtonEvent eventPosition) ifFalse: [ self deleteIfPopUp: aMouseButtonEvent. self activeHand newKeyboardFocus: prevKbdFocus; newMouseFocus: prevMouseFocus. ^ self ]. "No click outside, handle normally" (scrollBar includesPixel: aMouseButtonEvent eventPosition) ifTrue: [scrollBar mouseButton1Up: aMouseButtonEvent localPosition: localEventPosition] ifFalse: [super mouseButton1Up: aMouseButtonEvent localPosition: localEventPosition]. aMouseButtonEvent hand newMouseFocus: self </pre> A workable solution is to override mouseButtonXUp: methods to set back the focus and to dispatch manualy the mouse event to the scrollbar. It is a bit overkill. I don't know how to handle the situation more properly. Ideas?
