wxAuiToolBar resized according to its content

[luca]

Hello,

I am using wxWidgets 2.9.1 from last trunk of Subversion, and i have a wxAuiToolBar with some custom control (checkboxes and comboboxes) and a some labels. The problem is that when i change the content of the label making them longer than it were, the toolbar is not resized to a larger size, and the controls on the right of the larger label disappear. How to fix this issue?

Thanks,
Luca
