Signal
GtkWidget::query-tooltip
Declaration
gboolean
query_tooltip (
  GtkWidget* self,
  gint x,
  gint y,
  gboolean keyboard_mode,
  GtkTooltip* tooltip,
  gpointer user_data
)
Description [src]
Emitted when the widgets tooltip is about to be shown.
This happens when the GtkWidget:has-tooltip property
is TRUE and the hover timeout has expired with the cursor hovering
“above” widget; or emitted when widget got focus in keyboard mode.
Using the given coordinates, the signal handler should determine
whether a tooltip should be shown for widget. If this is the case
TRUE should be returned, FALSE otherwise.  Note that if
keyboard_mode is TRUE, the values of x and y are undefined and
should not be used.
The signal handler is free to manipulate tooltip with the therefore
destined function calls.
