CellRendererCombo

GtkCellRendererCombo renders text in a cell like GtkCellRendererText from which it is derived. But while GtkCellRendererText offers a simple entry to edit the text, GtkCellRendererCombo offers a GtkComboBox widget to edit the text. The values to display in the combo box are taken from the tree model specified in the "model" property.

The combo cell renderer takes care of adding a text cell renderer to the combo box and sets it to display the column specified by its "text-column" property. Further properties of the combo box can be set in a handler for the "editing-started" signal.

The GtkCellRendererCombo cell renderer was added in GTK+ 2.6.

class CellRendererCombo : CellRendererText {

protected

GtkCellRendererCombo* gtkCellRendererCombo;

GtkCellRendererCombo* getCellRendererComboStruct();

void* getStruct();

this(GtkCellRendererCombo* gtkCellRendererCombo);

void setStruct(GObject* obj);

int[string] connectedSignals;

void delegate(string, TreeIter, CellRendererCombo)[] onChangedListeners;

void addOnChanged(void delegate(string, TreeIter, CellRendererCombo) dlg, ConnectFlags connectFlags);

static void callBackChanged(GtkCellRendererCombo* comboStruct, gchar* pathString, GtkTreeIter* newIter, CellRendererCombo _cellRendererCombo);

this();

}

Constructors

this this(GtkCellRendererCombo* gtkCellRendererCombo): Sets our main struct and passes it to the parent class
this this(): Creates a new GtkCellRendererCombo. Adjust how text is drawn using object properties. Object properties can be set globally (with g_object_set()). Also, with GtkTreeViewColumn, you can bind a property to a value in a GtkTreeModel. For example, you can bind the "text" property on the cell renderer to a string value in the model, thus rendering a different string in each row of the GtkTreeView. Since 2.6

Functions

addOnChanged void addOnChanged(void delegate(string, TreeIter, CellRendererCombo) dlg, ConnectFlags connectFlags): This signal is emitted each time after the user selected an item in the combo box, either by using the mouse or the arrow keys. Contrary to GtkComboBox, GtkCellRendererCombo::changed is not emitted for changes made to a selected item in the entry. The argument new_iter corresponds to the newly selected item in the combo box and it is relative to the GtkTreeModel set via the model property on GtkCellRendererCombo. Note that as soon as you change the model displayed in the tree view, the tree view will immediately cease the editing operating. This means that you most probably want to refrain from changing the model until the combo cell renderer emits the edited or editing_canceled signal. Since 2.14

addOnEdited void addOnEdited(void delegate(string, string, CellRendererText) dlg, ConnectFlags connectFlags): This signal is emitted after renderer has been edited. It is the responsibility of the application to update the model and store new_text at the position indicated by path.
callBackEdited void callBackEdited(GtkCellRendererText* rendererStruct, gchar* path, gchar* newText, CellRendererText _cellRendererText): Undocumented in source. Be warned that the author may not have intended to support it.
setFixedHeightFromFont void setFixedHeightFromFont(int numberOfRows): Sets the height of a renderer to explicitly be determined by the "font" and "y_pad" property set on it. Further changes in these properties do not affect the height, so they must be accompanied by a subsequent call to this function. Using this function is unflexible, and should really only be used if calculating the size of a cell is too slow (ie, a massive number of cells displayed). If number_of_rows is -1, then the fixed height is unset, and the height is determined by the properties again.
