GtkFixedLayout is a layout manager which can place child widgets at fixed positions.

Most applications should never use this layout manager; fixed positioning and sizing requires constant recalculations on where children need to be positioned and sized. Other layout managers perform this kind of work internally so that application developers don't need to do it. Specifically, widgets positioned in a fixed layout manager will need to take into account:

• Themes, which may change widget sizes.

• Fonts other than the one you used to write the app will of course change the size of widgets containing text; keep in mind that users may use a larger font because of difficulty reading the default, or they may be using a different OS that provides different fonts.

• Translation of text into other languages changes its size. Also, display of non-English text will use a different font in many cases.

In addition, GtkFixedLayout does not pay attention to text direction and thus may produce unwanted results if your app is run under right-to-left languages such as Hebrew or Arabic. That is: normally GTK will order containers appropriately depending on the text direction, e.g. to put labels to the right of the thing they label when using an RTL language; GtkFixedLayout won't be able to do that for you.

Finally, fixed positioning makes it kind of annoying to add/remove UI elements, since you have to reposition all the other elements. This is a long-term maintenance problem for your application.

Constructor Details

FixedLayout

public FixedLayout(MemorySegment address)

Create a FixedLayout proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

FixedLayout

public FixedLayout()

Creates a new GtkFixedLayout.

Method Details

getType

public static Type getType()

Get the GType of the FixedLayout class

Returns:

the GType

asParent

protected FixedLayout 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 LayoutManager

builder

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

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