Summary0026895: AnchorDocking: Messages window either disappears or becomes very small in some situations
DescriptionThis is not 100% reproducible. I guess there are uninitialized variables involved or something similar.
The default layout without any anchordocklayout.xml contains source editor, messages window below it and Code Explorer on the right.
The Steps to Reproduce below assumes the default layout.

In case 1 the Messages window becomes small. It may be related to 0018538 but the effect is more dramatic. There must be a docked window on the left side that occupies all the vertical space from top to bottom.
After deleting the default anchordocklayout.xml and trying again with same steps ... I could not reproduce! Must be uninitialized memory.

In case 2 the Messages window disappears.
This one I can reproduce always.
Steps To ReproduceCase 1: Messages window becomes small.
1. Show OI (F11) and dock it on left side of Source editor.
2. Dock Messages window below Source editor. Now they are both on the right side of OI and OI's height is from top to bottom.
3. Resize the IDE by crabbing its corner. Messages window becomes very low.

Case 2: Message window disappears.
1. Do steps 1 and 2 of case 1.
2. Show Component list (Ctrl-Alt-P) and dock it on right side of Source editor. Now both Source editor and Component list are above Messages window. Messages window is between OI and Code exprorer side-ways.
3. Tools -> Save window layout as default.
4. Close and restart the IDE.
5. Resize the IDE by crabbing its corner. Messages window disappears. The 2 windows above it, SE and Code explorer, extend below the IDE's bottom edge and become partly invisible.
TagsNo tags attached.

This is reproducible only when "Scale on resize" is enabled.

Now I realized this is also a QT related issue. The same thing does not happen with GTK2 or Windows, not the same way anyway. How is the layout system different in QT?

I noticed the same thing happens with GlassDocking taken from CodeTyphon. It can be compiled and tested with standard Lazarus easily.
They have not made any big changes, mostly formatting.

Zeljko, where is the "Scale on resize" option?
I cannot reproduce this any more. I think it was solved by r51081.

It is somewhere in Options -> Anchordocking settings (or similar name), I don't use anchordocking so cannot point you to the right direction atm.
