TButton looks too small!
If you design a button in another widgetset with Autosize=Off it might happen that the button looks too small in Cocoa, and a number of people complained about this, such as in these BTS reports: .
If you don't care about the button size, just set AutoSize=True. If you want to have a custom width for the button, but wants to allow the LCL to choose the right Height so that the button will look good in Cocoa, then the solution in this case is to set the following properties in the Object Inspector:
- Constrains.MinWidth = Constrains.MaxWidth = your desired width.
