Pmw.PanedWidget() - frame subdivided into several resizable panes
A paned widget is a container megawidget which manages a number of resizable frames, known as panes. Each pane may act as the container for other widgets. The user may interactively resize the panes by dragging a small rectangle (the handle) or the line between the panes (the separator). The panes may be arranged horizontally or vertically. Each pane may have maximum and minimum limits of its size.
Each pane has the following options. These may be set when creating or configuring a pane. The value of each option may be an integer, which specifies a pane size in pixels, or a real number between 0.0 and 1.0, which specifies a pane size proportional to the size of the entire paned widget.
Frame, separator and handle components are created dynamically
insert() methods. The components are of type
Tkinter.Frame and are created with component groups of
Frame, Separator and Handle respectively.
insert()with before set to the current number of panes. The method returns the name component widget.
If the pane deleted was not the only pane in the paned widget, also delete the separator and handle components named separator-n and handle-n, where n is the number of panes remaining.
The new pane is created as a Tkinter.Frame component named name. If this is not the only pane, a separator and handle are also created as components named separator-n and handle-n, where n is one less than the number of panes. The method returns the name component widget.
If oriented vertically, set the height of the paned widget to the sum of the requested heights of all panes and set the width to the maximum requested width of all panes.
