gtk:tree-view-fixed-height-mode (object)

object -- a gtk:tree-view widget
enable -- true to enable fixed height mode

Accessor of the fixed-height-mode slot of the gtk:tree-view class. The gtk:tree-view-fixed-height-mode function returns whether fixed height mode is turned on for the tree view. The (setf gtk:tree-view-fixed-height-mode) function enables or disables the fixed height mode.

Fixed height mode speeds up the tree view by assuming that all rows have the same height. Only enable this option if all rows are the same height and all columns have the :fixed value of the gtk:tree-view-column-sizing enumeration. The gtk:tree-view implementation is deprecated since 4.10. Please do not use it in newly written code.
