CellRendererSpin
Renders a spin button in a cell
GtkCellRendererSpin
renders text in a cell like GtkCellRendererText
from which it is derived. But while GtkCellRendererText
offers a simple entry to edit the text, GtkCellRendererSpin
offers a GtkSpinButton
widget. Of course, that means that the text has to be parseable as a floating point number.
The range of the spinbutton is taken from the adjustment property of the cell renderer, which can be set explicitly or mapped to a column in the tree model, like all properties of cell renders. GtkCellRendererSpin
also has properties for the GtkCellRendererSpin:climb-rate
and the number of GtkCellRendererSpin:digits
to display. Other GtkSpinButton
properties can be set in a handler for the GtkCellRenderer::editing-started
signal.

Functions
Passes an activate event to the cell renderer for possible processing. Some cell renderers may use events; for example, GtkCellRendererToggle
toggles when it gets a mouse click.
Emits the "edited" signal. See onEdited.
Emits the "editing-canceled" signal. See onEditingCanceled.
Emits the "editing-started" signal. See onEditingStarted.
Gets the aligned area used by @cell inside @cell_area. Used for finding the appropriate edit and focus rectangle.
Retrieves the minimum and natural size of a cell taking into account the widget’s preference for height-for-width management.
Gets whether the cell renderer prefers a height-for-width layout or a width-for-height layout.
Translates the cell renderer state to GtkStateFlags
, based on the cell renderer and widget sensitivity, and the given GtkCellRenderer
State.
Checks whether the cell renderer can do something when activated.
This signal gets emitted when the user cancels the process of editing a cell. For example, an editable cell renderer could be written to cancel editing when the user presses Escape.
This signal gets emitted when a cell starts to be edited. The intended use of this signal is to do special setup on @editable, e.g. adding a GtkEntryCompletion
or setting up additional columns in a GtkComboBox
.
Sets the renderer’s alignment within its available space.
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 inflexible, 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.
Sets the renderer size to be explicit, independent of the properties set.
Sets the renderer’s padding.
Invokes the virtual render function of the GtkCellRenderer
. The three passed-in rectangles are areas in @cr. Most renderers will draw within
Starts editing the contents of this @cell, through a new GtkCellEditable
widget created by the GtkCellRenderer
Class.start_editing virtual function.
Informs the cell renderer that the editing is stopped. If @canceled is true, the cell renderer will emit the GtkCellRenderer
::editing-canceled signal.
