SYNOPSIS

    use Tk::DockFrame;

    $DockPort = $parent->DockPort();

    $DockPort->pack();

    $DockFrame = $parent->DockFrame
       (
        '-dock' => $DockPort,
        '-trimcount' => 1,
        '-sensitivity' => 10,
        '-decorate' => 0,
        '-trimgap' => 2
       );

    $DockFrame->Widget (...)->pack();

    ...

    Tk::MainLoop;

DESCRIPTION

Objects of class DockFrame are simple frames which can be made to "float" free as Toplevel widgets or packed as Frames. Dockframes can have any number of direct children but the favored use is to pack a single Frame based child widget and add widgets to that using any geometry manager.

DockPorts are simple frame widgets which must be managed by the packer. They normally have no width or height and are thus rendered invisible. DockFrame children of the same parentage, when dragged over them, will be converted from "floating" Toplevels into Frame widgets rendered within the DockPort, resizing it accordingly.

IMPORTANT UPDATE

The DockFrames are now managed WITHIN the DockPorts, therefore any geometry manager can be used with all the widgets described here

STANDARD OPTIONS

DockFrame

-background -borderwidth -relief -bg -width -height

DockPort

none

See Tk for details of the standard options.

WIDGET-SPECIFIC OPTIONS

Name: dock

Class: Dock

Switch: -dock

Used to "dock" a DockFrame to a DockPort. The parameter passed must be a reference to a DockPort and nothing else. If a DockPort is not specified in this manner on creation, then the DockFrame will initially "float" free.

Name: trimcount

Class: TrimCount

Switch: -trimcount

Specifies the number of button trim drag 'handles'. Specifying 0 will prevent attachment/detachment of the DockFrame.

Name: sensitivity

Class: Sensitivity

Switch: -sensitivity

The DockFrame will "dock" when it gets within the specified number of pixels of the DockPort.

Name: decorate

Class: Decorate

Switch: -decorate

Boolean value indicating whether or not to instruct the window manager to add decoration (titlebar, etc) to the undocked DockFrame. It is important to note here that, due to the nature of the event handling, dragging the DockFrame by the titlebar will not cause it to dock.

Name: trimgap

Class: Trimgap

Switch: -trimgap

This option specifies the number of pixels to leave between the "handles" and the first child widget

WIDGET METHODS

$DockFrame->dock ($DockPort)

Immediately docks the DockFrame to the specified DockPort

$DockFrame->undock()

Immediately undocks the DockFrame

BINDINGS

[1]

Pressing and holding the left mouse button on a DockFrame trim element allows movement of that DockFrame. If the DockFrame is "dragged" over a DockPort, it will "dock" and dragging will cease until the "handle" is released and then selected again.
