GI.Gtk.Objects.HandleBox

The HandleBox widget allows a portion of a window to be "torn off". It is a bin widget which displays its child and a handle that the user can drag to tear off a separate window (the “float window”) containing the child widget. A thin “ghost” is drawn in the original location of the handlebox. By dragging the separate window back to its original location, it can be reattached.

When reattaching, the ghost and float window, must be aligned along one of the edges, the “snap edge”. This either can be specified by the application programmer explicitly, or GTK+ will pick a reasonable default based on the handle position.

To make detaching and reattaching the handlebox as minimally confusing as possible to the user, it is important to set the snap edge so that the snap edge does not move when the handlebox is deattached. For instance, if the handlebox is packed at the bottom of a VBox, then when the handlebox is detached, the bottom edge of the handlebox's allocation will remain fixed as the height of the handlebox shrinks, so the snap edge should be set to PositionTypeBottom.

t'GI.Gtk.Objects.HandleBox.HandleBox' has been deprecated. It is very specialized, lacks features
to make it useful and most importantly does not fit well into modern
application design. Do not use it. There is no replacement.

-> m ()

Deprecated: (Since version 3.4)tHandleBox has been deprecated.

Sets the side of the handlebox where the handle is drawn.

setShadowType

handleBoxSetShadowType

Arguments

:: (HasCallStack, MonadIO m, IsHandleBox a)

=> a

-> ShadowType

type: the shadow type.

-> m ()

Deprecated: (Since version 3.4)tHandleBox has been deprecated.

setSnapEdge

handleBoxSetSnapEdge

Arguments

:: (HasCallStack, MonadIO m, IsHandleBox a)

-> m ()

Deprecated: (Since version 3.4)tHandleBox has been deprecated.

Sets the snap edge of a handlebox. The snap edge is the edge of the detached child that must be aligned with the corresponding edge of the “ghost” left behind when the child was detached to reattach the torn-off window. Usually, the snap edge should be chosen so that it stays in the same place on the screen when the handlebox is torn off.

If the snap edge is not set, then an appropriate value will be guessed from the handle position. If the handle position is PositionTypeRight or PositionTypeLeft, then the snap edge will be PositionTypeTop, otherwise it will be PositionTypeLeft.
