Qt 4.8 (Expand/Collapse widget)

[Boris1980]

Good Morning guys,

i want to implement a VerticalLayout with 2 Widgets, in which the left widget can be colapse to a small bar (and the right widget will use the whole space).
When i click tot the collapsed bar, the left widget expands to the old size.

(sorry for my bad english, i hop some now what i mean) iam using qt4.8

Hi,

Do you mean something a bit like QSplitter ?

[Boris1980]

yeah, that lock fine:) but how can i collapse /expand is with a button click?
an mouse -drag (move splitter) should be permit

You could detect the double click on the handler and collapse the left widget.
