// Unfortunately, I couldn't get the TDEToolBar to work nicely when it
|
|
// was floating, so I was forced to write these classes. I'm not sure whether
|
|
// I didn't try hard enough or ... and I've forgotten what the problems were
|
|
// now.
|
|
|
|
// The problem with using this is that it will not dock as a normal toolbar.
|
|
// I'm not convince that this is a real problem though.
|
|
|
|
// So, if you can get it to work as a TDEToolBar, and it works well when the
|
|
// app is running, then all these classes can be removed.
|
|
|
|
// This code is very specific to the internal debugger in tdevelop.

// This just allows the user to click on the toolbar and drag it somewhere else.
|
|
// I would have preferred to use normal decoration on the toolbar and removed
|
|
// the iconify, close, etc buttons from the window title but again I kept running
|
|
// into problems. Instead, I used no decoration and this class. Also this looks
