Name
qadjustsize — Adjust widget size to contents
Syntax
qadjustsize [widget]
Description
The qadjustsize command tells the widget to recalculate its geometry based on its contents. This command is often used to perform a size adjustment to windows that has had its interior changed, usually as a result of widgets being removed or added after the widget's initial display.
The qadjustsize is not always needed. QTcl will resize widgets quite well on its own without an explicit call to qadjustsize.
See also qresize and qsetfixedsize. These commands use pixel based size-specifications.
Arguments
widget
Unknown macro: {indent}
Target widget. If not given the current widget is used.

proc show_label {} {
qshow $::label
qadjustsize $::w
}
# Create toplevel window
set w [qwidget ]
qsetattribute $w deleteonclose
