Summary0014061: TToolBar doesn't resize properly
DescriptionThese problems have been observed when a TToolBar is or should be resized:

1) A wrapable toolbar doesn't change in Height when buttons wrap.
2) ToolButtons can loose their (autosize) Width.

See Lazarus examples/dockmanager/toolbar/test1 demo project.
Additional Information[1] Wrapable only affects the visibility of wrapped buttons, but seems not to adjust the Height of the toolbar, nor the Top of wrapped buttons.

[2] Happens randomly with the win32 widgetset, seems not to occur with gtk2.
See Lazarus examples/dockmanager/easytree/easydocking demo project, try docking and undocking a notebook. The notebook can be dragged by dragging its toolbar.

Possibly related issue: programmatically added buttons are added *before* existing buttons, should be *after*. I found no way to rearrange the buttons programmatically.
TagsNo tags attached.

ToolButtonLast.patch adds new buttons to the right of the existing buttons.
This is achieved by initializing NewButton.Left to an value past lastbutton.right.

When an index is known for the new button, its Left value could be derived from the button[newindex-1].Left plus a small delta (+1?), to ensure that the new button is aligned after this button. (Just an idea)

I also tried to retain the current width when AutoSize is true, but this seems not to work :-(

1. Is fixed in r20849
2. Needs a simplier example. Ideally 1 form + 1 toolbar + 1 button to generate wrong toolbar configuation.

And after all this are different issues. I would suggest to open separate bug report for the second issue.

And please test and close if the first issue is fixed now. To test you need to set ToolBar.AutoSize = True
