Revision 4230
Date: 2008-07-04 10:10:15 -0700 (Fri, 04 Jul 2008)
Author: Ed
Trac: http://svn.dabodev.com/trac/dabo/changeset/4230
Changed:
U trunk/dabo/ui/uiwx/dForm.py
Log:
Added the FloatingPanel property. This references a borderless dialog that can
be used similarly to a context menu, but which can contain any controls you
want. Additionally, it will guarantee that it is displayed completely within
the available screen real estate.
It has two properties itself:
Above: by default the dialog is positioned below its owning control.
This changes the behavior so that it is positioned above the control.
Owner: this is the control used to position the dialog.
Typical usage (written in a custom control):
fp = self.Form.FloatingPanel
fp.clear()
# Add controls
ctrl = dabo.ui.dTextBox(fp, ...)
ctrl2 = ...
# Set the Owner to the control
fp.Owner = self
fp.show()
The controls in the FloatingPanel should hide or release it, depending on
whether you expect to re-use it. See the update to dDateTextBox for an
implementation of it.
