The FindPanel in TextEdit has in the bottom left corner a button "Replace All" which changes to "In Selection" when the ⌥-key is pressed.

How is this done? I want to have such a changing button in some of my own panels.

Well, I did have a look at the flagsChanged: method of NSResponder.

My window has the following responder chain:

<NSTextView: 0x6a04a0> // field editor of myTextField
<_NSKeyboardFocusClipView: 0x6b5920>
<NSTextField: 0x6866a0> // myTextField
<NSView: 0x686ff0> // contentView
<NSPanel: 0x6a23c0> // window
(Mail.app did again eat all newlines when I pasted the text above. How can this be avoided? This kind of starts to get annoying.)


Now the question: where to override flagsChanged: ?
Or subclass NSPanel and override sendEvent ?
Or put a subclass of NSResponder on top of the responder chain? How to keep it there (overriding makeFirstResponder in NSWindow?)



Kind regards,

Gerriet.
