That's the default size of the control. The constraints are applied after. A TBevel can be shrinked to less than 50.

Re: [Lazarus] Centered elements in autosize enabled panel. Possible?
Most of my applications are for RightToLeft (Hebrew) and TToolBar and TStatusBar don't support RightToLeft so I use this technique to make my own. I use the Align:= alLeft/alRight method though. And I use TPanel for dividers. On Mon, Nov 11, 2013 at 12:51 PM, Valdas Jankūnas wrote: > 2013.11.11 06:06, Avishai rašė: > > Could you use a TPanel in place of the TBevel?

Well? I forgot that I had set Constraints.MaxHeight:= 24 before I set b orderSpacing.Around:= 4. Then I changed MaxHeight:= 20 and it went back to Height:= 50.

Re: [Lazarus] Centered elements in autosize enabled panel. Possible?
What I don't like about ChildSizing is if you need to change the order of controls it can be difficult. And here's something you should try. Have a TPanel as one of the Children - get everything set the way you want with ChildSizing - now add a TLabel to the TPanel. Using LeftAlign it's only a matter of dragging the control to the location you want. BorderSpacing and Constraints gives me all the control I need (so far - I'm still playing with it).
