Virtual Method

GtkWidgetmeasure

Declaration [src]

void
measure (
  GtkWidget* widget,
  GtkOrientation orientation,
  int for_size,
  int* minimum,
  int* natural,
  int* minimum_baseline,
  int* natural_baseline
)

Description [src]

Measures widget in the orientation orientation and for the given for_size.

As an example, if orientation is GTK_ORIENTATION_HORIZONTAL and for_size is 300, this functions will compute the minimum and natural width of widget if it is allocated at a height of 300 pixels.

See GtkWidget’s geometry management section for a more details on implementing GtkWidgetClass.measure().

Parameters

`orientation`	`GtkOrientation`
	The orientation to measure.
`for_size`	`int`
	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`	`int*`
	Location to store the minimum size.
	The argument will be set by the function.
	The argument can be `NULL`.
	The called function takes ownership of the data, and is responsible for freeing it.
`natural`	`int*`
	Location to store the natural size.
	The argument will be set by the function.
	The argument can be `NULL`.
	The called function takes ownership of the data, and is responsible for freeing it.
`minimum_baseline`	`int*`
	Location to store the baseline position for the minimum size.
	The argument will be set by the function.
	The argument can be `NULL`.
	The called function takes ownership of the data, and is responsible for freeing it.
`natural_baseline`	`int*`
	Location to store the baseline position for the natural size.
	The argument will be set by the function.
	The argument can be `NULL`.
	The called function takes ownership of the data, and is responsible for freeing it.
