PointerInterface

public class Scrollable
extends Interface

An interface for widgets with native scrolling ability.

To implement this interface you should override the
[property@Gtk.Scrollable:hadjustment] and
[property@Gtk.Scrollable:vadjustment] properties.

## Creating a scrollable widget

All scrollable widgets should do the following.

- When a parent widget sets the scrollable child widget’s adjustments,
the widget should connect to the [signal@Gtk.Adjustment::value-changed]
signal. The child widget should then populate the adjustments’ properties
as soon as possible, which usually means queueing an allocation right away
and populating the properties in the [vfunc@Gtk.Widget.size_allocate]
implementation.

- Because its preferred size is the size for a fully expanded widget,
the scrollable widget must be able to cope with underallocations.
This means that it must accept any value passed to its
[vfunc@Gtk.Widget.size_allocate] implementation.

- When the parent allocates space to the scrollable child widget,
the widget must ensure the adjustments’ property values are correct and up
to date, for example using [method@Gtk.Adjustment.configure].

- When any of the adjustments emits the [signal@Gtk.Adjustment::value-changed]
signal, the scrollable widget should scroll its contents.

Scrollable

public Scrollable(PointerContainer pointer)

Methodendetails

getClassHandler

public static ClassHandler getClassHandler()

getBorder

public boolean getBorder(@Nonnull
 Border border)

Returns the size of a non-scrolling border around the
outside of the scrollable.

An example for this would be treeview headers. GTK can use
this information to display overlaid graphics, like the
overshoot indication, at the right position.

Parameter:

border - return location for the results

Gibt zurück:

%TRUE if @border has been set

getHadjustment

public Adjustment getHadjustment()

Retrieves the `GtkAdjustment` used for horizontal scrolling.

Gibt zurück:

horizontal `GtkAdjustment`.

getHscrollPolicy

public int getHscrollPolicy()

Gets the horizontal `GtkScrollablePolicy`.

Gibt zurück:

The horizontal `GtkScrollablePolicy`.

getVadjustment

public Adjustment getVadjustment()

Retrieves the `GtkAdjustment` used for vertical scrolling.

Gibt zurück:

vertical `GtkAdjustment`.

getVscrollPolicy

public int getVscrollPolicy()

Gets the vertical `GtkScrollablePolicy`.

Gibt zurück:

The vertical `GtkScrollablePolicy`.

setHadjustment

public void setHadjustment(@Nullable
 Adjustment hadjustment)

Sets the horizontal adjustment of the `GtkScrollable`.

Parameter:

hadjustment - a `GtkAdjustment`

setHscrollPolicy

public void setHscrollPolicy(int policy)

Sets the `GtkScrollablePolicy`.

The policy determines whether horizontal scrolling should start
below the minimum width or below the natural width.

Parameter:

policy - the horizontal `GtkScrollablePolicy`

setVadjustment

public void setVadjustment(@Nullable
 Adjustment vadjustment)

Sets the vertical adjustment of the `GtkScrollable`.

Parameter:

vadjustment - a `GtkAdjustment`

setVscrollPolicy

public void setVscrollPolicy(int policy)

Sets the `GtkScrollablePolicy`.

The policy determines whether vertical scrolling should start
below the minimum height or below the natural height.

Parameter:

policy - the vertical `GtkScrollablePolicy`

getTypeID

public static long getTypeID()

getParentTypeID

public static long getParentTypeID()

getTypeSize

public static TypeSystem.TypeSize getTypeSize()

getParentTypeSize

public static TypeSystem.TypeSize getParentTypeSize()

getInstanceSize

public static int getInstanceSize()
