i.e. when wrap-width > 0. This was only being done for non-grid cases. So, ComboBoxes in grid mode did not indicate their selection when popped up and required users to keynav from ‘nothing’ (at the top-left) to the item they wanted to select. By selecting the active item in advance, now it’s highlighted & acts as the starting point for keynav around the grid

* SECTION:gtkcombobox
|
||
* @Short_description: A widget used to choose from a list of items
|
||
* @Title: GtkComboBox
|
||
* @See_also: #GtkComboBoxText, #GtkTreeModel, #GtkCellRenderer
|
||
*
|
||
* A GtkComboBox is a widget that allows the user to choose from a list of
|
||
* valid choices. The GtkComboBox displays the selected choice. When
|
||
* activated, the GtkComboBox displays a popup which allows the user to
|
||
* make a new choice. The style in which the selected value is displayed,
|
||
* and the style of the popup is determined by the current theme. It may
|
||
* be similar to a Windows-style combo box.
|
||
*
|
||
* The GtkComboBox uses the model-view pattern; the list of valid choices
|
||
* is specified in the form of a tree model, and the display of the choices
|
||
* can be adapted to the data in the model by using cell renderers, as you
|
||
* would in a tree view. This is possible since GtkComboBox implements the
|
||
* #GtkCellLayout interface. The tree model holding the valid choices is
|
||
* not restricted to a flat list, it can be a real tree, and the popup will
|
||
* reflect the tree structure.
|
||
*
|
||
* To allow the user to enter values not in the model, the “has-entry”
|
||
* property allows the GtkComboBox to contain a #GtkEntry. This entry
|
||
* can be accessed by calling gtk_bin_get_child() on the combo box.
|
||
*
|
||
* For a simple list of textual choices, the model-view API of GtkComboBox
|
||
* can be a bit overwhelming. In this case, #GtkComboBoxText offers a
|
||
* simple alternative. Both GtkComboBox and #GtkComboBoxText can contain
|
||
* an entry.
|
||
*
|
||
* # CSS nodes

|
||

|
||
*
|
||
* A normal combobox contains a box with the .linked class, a button
|
||
* with the .combo class and inside those buttons, there are a cellview and
|
||
* an arrow.

|

|
||
* A GtkComboBox with an entry has a single CSS node with name combobox. It
|
||
* contains a bx with the .linked class and that box contains an entry and a
|
||
* button, both with the .combo class added.
|
||
* The button also contains another node with name arrow.
