public static final String APPLY_ATTRIBUTES

Apply the cell attributes to the cells. This is
implemented as a signal and generally `GtkCellArea` subclasses don't
need to implement it since it is handled by the base class.
See CellAreaClass.OnApplyAttributes.onApplyAttributes(ch.bailu.gtk.lib.handler.CallbackHandler, ch.bailu.gtk.gtk.CellArea, ch.bailu.gtk.gtk.TreeModel, ch.bailu.gtk.gtk.TreeIter, boolean, boolean)

it prefers to be allocated in %GTK_SIZE_REQUEST_HEIGHT_FOR_WIDTH or
%GTK_SIZE_REQUEST_WIDTH_FOR_HEIGHT mode.
See CellAreaClass.OnGetRequestMode.onGetRequestMode(ch.bailu.gtk.lib.handler.CallbackHandler, ch.bailu.gtk.gtk.CellArea)

GET_PREFERRED_WIDTH

public static final String GET_PREFERRED_WIDTH

Calculates the minimum and natural width of the
areas cells with the current attributes applied while considering
the particular layouting details of the said `GtkCellArea`. While
requests are performed over a series of rows, alignments and overall
minimum and natural sizes should be stored in the corresponding
`GtkCellAreaContext`.
See CellAreaClass.OnGetPreferredWidth.onGetPreferredWidth(ch.bailu.gtk.lib.handler.CallbackHandler, ch.bailu.gtk.gtk.CellArea, ch.bailu.gtk.gtk.CellAreaContext, ch.bailu.gtk.gtk.Widget, ch.bailu.gtk.type.Int, ch.bailu.gtk.type.Int)

GET_PREFERRED_HEIGHT_FOR_WIDTH

public static final String GET_PREFERRED_HEIGHT_FOR_WIDTH

Calculates the minimum and natural height
for the area if the passed @context would be allocated the given width.
When implementing this virtual method it is safe to assume that @context
has already stored the aligned cell widths for every `GtkTreeModel` row
that @context will be allocated for since this information was stored
at `GtkCellAreaClass.get_preferred_width()` time. This virtual method
should also store any necessary alignments of cell heights for the
case that the context is allocated a height.
See CellAreaClass.OnGetPreferredHeightForWidth.onGetPreferredHeightForWidth(ch.bailu.gtk.lib.handler.CallbackHandler, ch.bailu.gtk.gtk.CellArea, ch.bailu.gtk.gtk.CellAreaContext, ch.bailu.gtk.gtk.Widget, int, ch.bailu.gtk.type.Int, ch.bailu.gtk.type.Int)

Siehe auch:

• Konstantenfeldwerte

GET_PREFERRED_HEIGHT

public static final String GET_PREFERRED_HEIGHT

Calculates the minimum and natural height of the
areas cells with the current attributes applied. Essentially this is
the same as `GtkCellAreaClass.get_preferred_width()` only for areas
that are being requested as %GTK_SIZE_REQUEST_WIDTH_FOR_HEIGHT.
See CellAreaClass.OnGetPreferredHeight.onGetPreferredHeight(ch.bailu.gtk.lib.handler.CallbackHandler, ch.bailu.gtk.gtk.CellArea, ch.bailu.gtk.gtk.CellAreaContext, ch.bailu.gtk.gtk.Widget, ch.bailu.gtk.type.Int, ch.bailu.gtk.type.Int)

Siehe auch:

• Konstantenfeldwerte

GET_PREFERRED_WIDTH_FOR_HEIGHT

public static final String GET_PREFERRED_WIDTH_FOR_HEIGHT

Calculates the minimum and natural width
for the area if the passed @context would be allocated the given
height. The same as `GtkCellAreaClass.get_preferred_height_for_width()`
only for handling requests in the %GTK_SIZE_REQUEST_WIDTH_FOR_HEIGHT
mode.
See CellAreaClass.OnGetPreferredWidthForHeight.onGetPreferredWidthForHeight(ch.bailu.gtk.lib.handler.CallbackHandler, ch.bailu.gtk.gtk.CellArea, ch.bailu.gtk.gtk.CellAreaContext, ch.bailu.gtk.gtk.Widget, int, ch.bailu.gtk.type.Int, ch.bailu.gtk.type.Int)

SET_CELL_PROPERTY

public static final String SET_CELL_PROPERTY

This should be implemented to handle changes in child
cell properties for a given `GtkCellRenderer` that were previously
installed on the `GtkCellAreaClass` with gtk_cell_area_class_install_cell_property().
See CellAreaClass.OnSetCellProperty.onSetCellProperty(ch.bailu.gtk.lib.handler.CallbackHandler, ch.bailu.gtk.gtk.CellArea, ch.bailu.gtk.gtk.CellRenderer, int, ch.bailu.gtk.gobject.Value, ch.bailu.gtk.gobject.ParamSpec)

GET_CELL_PROPERTY

public static final String GET_CELL_PROPERTY

This should be implemented to report the values of
child cell properties for a given child `GtkCellRenderer`.
See CellAreaClass.OnGetCellProperty.onGetCellProperty(ch.bailu.gtk.lib.handler.CallbackHandler, ch.bailu.gtk.gtk.CellArea, ch.bailu.gtk.gtk.CellRenderer, int, ch.bailu.gtk.gobject.Value, ch.bailu.gtk.gobject.ParamSpec)

Siehe auch:

• Konstantenfeldwerte

FOCUS

public static final String FOCUS

This virtual method should be implemented to navigate focus from
cell to cell inside the `GtkCellArea`. The `GtkCellArea` should move
focus from cell to cell inside the area and return %FALSE if focus
logically leaves the area with the following exceptions: When the
area contains no activatable cells, the entire area receives focus.
Focus should not be given to cells that are actually “focus siblings”
of other sibling cells (see gtk_cell_area_get_focus_from_sibling()).
Focus is set by calling gtk_cell_area_set_focus_cell().
See CellAreaClass.OnFocus.onFocus(ch.bailu.gtk.lib.handler.CallbackHandler, ch.bailu.gtk.gtk.CellArea, int)

IS_ACTIVATABLE

public static final String IS_ACTIVATABLE

Returns whether the `GtkCellArea` can respond to
`GtkCellAreaClass.activate()`, usually this does not need to be
implemented since the base class takes care of this however it can
be enhanced if the `GtkCellArea` subclass can handle activation in
other ways than activating its `GtkCellRenderers`.

getFieldGetPreferredWidth

public ch.bailu.gtk.gtk.JnaCellAreaClass.OnGetPreferredWidth getFieldGetPreferredWidth()

Calculates the minimum and natural width of the
areas cells with the current attributes applied while considering
the particular layouting details of the said `GtkCellArea`. While
requests are performed over a series of rows, alignments and overall
minimum and natural sizes should be stored in the corresponding
`GtkCellAreaContext`.
See CellAreaClass.OnGetPreferredWidth.onGetPreferredWidth(ch.bailu.gtk.lib.handler.CallbackHandler, ch.bailu.gtk.gtk.CellArea, ch.bailu.gtk.gtk.CellAreaContext, ch.bailu.gtk.gtk.Widget, ch.bailu.gtk.type.Int, ch.bailu.gtk.type.Int)

setFieldGetPreferredHeightForWidth

public void setFieldGetPreferredHeightForWidth(CellAreaClass.OnGetPreferredHeightForWidth get_preferred_height_for_width)

Calculates the minimum and natural height
for the area if the passed @context would be allocated the given width.
When implementing this virtual method it is safe to assume that @context
has already stored the aligned cell widths for every `GtkTreeModel` row
that @context will be allocated for since this information was stored
at `GtkCellAreaClass.get_preferred_width()` time. This virtual method
should also store any necessary alignments of cell heights for the
case that the context is allocated a height.

public void setFieldGetPreferredHeight(CellAreaClass.OnGetPreferredHeight get_preferred_height)

Calculates the minimum and natural height of the

that are being requested as %GTK_SIZE_REQUEST_WIDTH_FOR_HEIGHT.

This should be implemented to handle changes in child
cell properties for a given `GtkCellRenderer` that were previously
installed on the `GtkCellAreaClass` with gtk_cell_area_class_install_cell_property().
See CellAreaClass.OnSetCellProperty.onSetCellProperty(ch.bailu.gtk.lib.handler.CallbackHandler, ch.bailu.gtk.gtk.CellArea, ch.bailu.gtk.gtk.CellRenderer, int, ch.bailu.gtk.gobject.Value, ch.bailu.gtk.gobject.ParamSpec)

setFieldFocus

public void setFieldFocus(CellAreaClass.OnFocus focus)

This virtual method should be implemented to navigate focus from
cell to cell inside the `GtkCellArea`. The `GtkCellArea` should move
focus from cell to cell inside the area and return %FALSE if focus
logically leaves the area with the following exceptions: When the
area contains no activatable cells, the entire area receives focus.
Focus should not be given to cells that are actually “focus siblings”
of other sibling cells (see gtk_cell_area_get_focus_from_sibling()).
Focus is set by calling gtk_cell_area_set_focus_cell().
See CellAreaClass.OnFocus.onFocus(ch.bailu.gtk.lib.handler.CallbackHandler, ch.bailu.gtk.gtk.CellArea, int)

Returns whether the `GtkCellArea` can respond to

implemented since the base class takes care of this however it can
be enhanced if the `GtkCellArea` subclass can handle activation in
other ways than activating its `GtkCellRenderers`.
