Method

GtkWidgettranslate_coordinates

Declaration [src]

gboolean
gtk_widget_translate_coordinates (
  GtkWidget* src_widget,
  GtkWidget* dest_widget,
  gint src_x,
  gint src_y,
  gint* dest_x,
  gint* dest_y
)

Description [src]

Translate coordinates relative to src_widget’s allocation to coordinates relative to dest_widget’s allocations. In order to perform this operation, both widgets must be realized, and must share a common toplevel.

Parameters

`dest_widget`	`GtkWidget`
	A `GtkWidget`.
	The data is owned by the caller of the function.
`src_x`	`gint`
	X position relative to `src_widget`.
`src_y`	`gint`
	Y position relative to `src_widget`.
`dest_x`	`gint*`
	Location to store X position relative to `dest_widget`.
	The argument will be set by the function.
	The argument can be `NULL`.
`dest_y`	`gint*`
	Location to store Y position relative to `dest_widget`.
	The argument will be set by the function.
	The argument can be `NULL`.

Return value

Returns:	`gboolean`
	`FALSE` if either widget was not realized, or there was no common ancestor. In this case, nothing is stored in `dest_x` and `dest_y`. Otherwise `TRUE`.
