public class Frame
extends Widget
implements Accessible, Buildable, ConstraintTarget

GtkFrame is a widget that surrounds its child with a decorative frame and an optional label.

If present, the label is drawn inside the top edge of the frame. The horizontal position of the label can be controlled with setLabelAlign(float).

GtkFrame clips its child. You can use this to add rounded corners to widgets, but be aware that it also cuts off shadows.

GtkFrame as GtkBuildable
The GtkFrame implementation of the GtkBuildable interface supports placing a child in the label position by specifying “label” as the “type” attribute of a <child> element. A normal content child can be specified without specifying a <child> type attribute.

An example of a UI definition fragment with GtkFrame:

<object class="GtkFrame">
   <child type="label">
     <object class="GtkLabel" id="frame_label"/>
   </child>
   <child>
     <object class="GtkEntry" id="frame_content"/>
   </child>
 </object>
 

CSS nodes

 frame
 ├── <label widget>
 ╰── <child>
 

GtkFrame has a main CSS node with name “frame”, which is used to draw the visible border. You can set the appearance of the border using CSS properties like “border-style” on this node.

Accessibility
GtkFrame uses the GTK_ACCESSIBLE_ROLE_GROUP role.

Constructor Details

Frame

public Frame(MemorySegment address)

Create a Frame proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Frame

public Frame(@Nullable
 @Nullable String label)

Creates a new GtkFrame, with optional label label.

If label is null, the label is omitted.

Parameters:

label - the text to use as the label of the frame

Frame

public Frame()

Calls Frame(java.lang.String) with label = null

Method Details

getType

public static Type getType()

Get the GType of the Frame class

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected Frame asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class Widget

getChild

public Widget getChild()

Gets the child widget of this Frame.

Returns:

the child widget of this Frame

getLabel

public String getLabel()

Returns the frame labels text.

If the frame's label widget is not a GtkLabel, null is returned.

Returns:

the text in the label, or null if there was no label widget or the label widget was not a GtkLabel. This string is owned by GTK and must not be modified or freed.

getLabelAlign

public float getLabelAlign()

Retrieves the X alignment of the frame’s label.

Returns:

the frames X alignment

getLabelWidget

public Widget getLabelWidget()

Retrieves the label widget for the frame.

Returns:

the label widget

setChild

public void setChild(@Nullable
 @Nullable Widget child)

Sets the child widget of this Frame.

Parameters:

child - the child widget

setLabel

public void setLabel(@Nullable
 @Nullable String label)

Creates a new GtkLabel with the label and sets it as the frame's label widget.

Parameters:

label - the text to use as the label of the frame

setLabelAlign

public void setLabelAlign(float xalign)

Sets the X alignment of the frame widget’s label.

The default value for a newly created frame is 0.0.

Parameters:

xalign - The position of the label along the top edge of the widget. A value of 0.0 represents left alignment; 1.0 represents right alignment.

setLabelWidget

public void setLabelWidget(@Nullable
 @Nullable Widget labelWidget)

Sets the label widget for the frame.

This is the widget that will appear embedded in the top edge of the frame as a title.

Parameters:

labelWidget - the new label widget

computeChildAllocation

protected void computeChildAllocation(Allocation allocation)

builder

public static Frame.Builder<? extends Frame.Builder> builder()

A Frame.Builder object constructs a Frame with the specified properties. Use the various set...() methods to set properties, and finish construction with Frame.Builder.build().
