Class SizeGroup


public class SizeGroup
extends GObject

SizeGroup provides a mechanism for grouping a number of widgets together so they all request the same amount of space. This is typically useful when you want a column of widgets to have the same size, but you can't use a Table widget.

In detail, the size requested for each widget in a SizeGroup is the maximum of the sizes that would have been requested for each widget in the size group if they were not in the size group. The mode of the size group (see setMode(SizeGroupMode) determines whether this applies to the horizontal size, the vertical size, or both sizes.

Note that size groups only affect the amount of space requested, not the size that the widgets finally receive. If you want the widgets in a SizeGroup to actually be the same size, you need to pack them in such a way that they get the size they request and not more. For example, if you are packing your widgets into a table, you would not include the GTK_FILL flag.

Widgets can be part of multiple size groups; GTK+ will compute the horizontal size of a widget from the horizontal requisition of all widgets that can be reached from the widget by a chain of size groups of type GTK_SIZE_GROUP_HORIZONTAL or GTK_SIZE_GROUP_BOTH, and the vertical size from the vertical requisition of all widgets that can be reached from the widget by a chain of size groups of type GTK_SIZE_GROUP_VERTICAL or GTK_SIZE_GROUP_BOTH.

Constructor Details

SizeGroup

public SizeGroup(SizeGroupMode mode)

Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.

Create a new SizeGroup
Parameters:
mode - The mode for the new Size Group

Method Details

addWidget

public void addWidget(Widget widget)

Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.

Adds a widget to the SizeGroup. In the future, the requisition of the widget will be determined as the maximum of its requisition and the requisition of the other widgets in the size group. Whether this applies horizontally, vertically, or in both directions depends on the mode of the size group. See setMode(SizeGroupMode).
Parameters:
widget - The Widget to add.

getType

public static Type getType()

Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.

Retrieve the runtime type used by the GLib library.

removeWidget

public void removeWidget(Widget widget)

Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.

Removes a widget from the group
Parameters:
widget - The widget to remove

setMode

public void setMode(SizeGroupMode mode)

Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.

Sets the SizeGroupMode of the size group. The mode of the size group determines whether the widgets in the size group should all have the same horizontal requisition (SizeGroupMode.HORIZONTAL) all have the same vertical requisition (SizeGroupMode.VERTICAL), or should all have the same requisition in both directions (SizeGroupMode.BOTH).
Parameters:
mode - The mode to set for the SizeGroup
