Thanks for advices, i added them to my work notes.
Working with Spec i found another problem:
I create a window with simple layout: menu + custom morph. I want my morph to
do some interactive work for me - it must display data and handle mouse
down\move\wheel.
The problem is: when i start the morph alone - it works. When i start my custom
morph inside the spec layout, it doesn't handle mouse events or sometimes
handles them randomly.
custom morph is a subclass of Morph, initialize widgets and defaultSpec are
very simple:
initializeWidgets
menu := self instantiate: MenuModel.
self setupMenu. <- I added menu items here.
menu applyTo: self.
locationField := LocationFieldMorph new asSpecAdapter.
defaultSpec
<spec: #default>
^ SpecLayout composed
newColumn:
[ :col |
col
newRow: [ :row | row add: #menu ] height: 32;
newRow: [ :row | row add: #locationField ] ]
yourself
all stuff in LocationFieldMorph (my custom morph) is done as described in
"Pharo By Example" and works fine when not arranged in Spec layout. What is
wrong?
Few other questions:
- how to switch focus between controls in Spec layout programmatically? (for
example, i need one of the controls to become in focus)
- how to determine whether a control is in focus or not? (i want to know if my
custom morph widget is in focus and draw a sign to show that fact to user)
