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.
This signal is emitted after @renderer has been edited.
#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.
The #GtkCellRendererSpin cell renderer was added in GTK+ 2.10.
