[Lazarus] TCoolBar improvements

Hi,

With all widgetsets it is possible to drag and resize bands, only the
cursor is wrong.
 
I still cannot reproduce. I don't know why it happens, in the code is used only crDefault, crHSplit and crDrag.

I see. I'll try to do something with it.
 
Coincidentaly, before two hours I installed Delphi7 Personal Edition to Wine and their implementation of TCoolBar isn't perfect too. For example, I can drag control away from band (on the second attempt). Also, when I put button on CoolBar it creates new band (it's OK) but it resizes the button to the full width of the CoolBar, which is pretty ugly. I tried to have more bands side by side in design time and in run time and I don't know how to it. II can only have each band on new line. Maybe it's possible only from code. But I believe it's possible somehow otehrwise the property Break shoudln't make sense.
 
On the other hand, TControlBar works fine in Delphi. That's where we loose yet. :D
 
I'll try to improve both. 
 
 
Have a nice day.

PS: Did anyone try ECControls on Carbon already?
