Method Details

onMeasure

void onMeasure(CallbackHandler __self,
 @Nonnull
 Widget widget,
 int orientation,
 int for_size,
 @Nullable
 Int minimum,
 @Nullable
 Int natural,
 @Nullable
 Int minimum_baseline,
 @Nullable
 Int natural_baseline)

Parameters:

widget - A `GtkWidget` instance

orientation - the orientation to measure

for_size - Size for the opposite of @orientation, i.e. if @orientation is %GTK_ORIENTATION_HORIZONTAL, this is the height the widget should be measured with. The %GTK_ORIENTATION_VERTICAL case is analogous. This way, both height-for-width and width-for-height requests can be implemented. If no size is known, -1 can be passed.

minimum - location to store the minimum size

natural - location to store the natural size

minimum_baseline - location to store the baseline position for the minimum size, or -1 to report no baseline

natural_baseline - location to store the baseline position for the natural size, or -1 to report no baseline
