Method
Pango.Layout.xy_to_index
Declaration [src]
gboolean
pango_layout_xy_to_index (
  PangoLayout* layout,
  int x,
  int y,
  int* index_,
  int* trailing
)
Description [src]
Converts from X and Y position within a layout to the byte index to the character at that logical position.
If the Y position is not inside the
layout, the closest position is chosen (the position will be clamped
inside the layout). If the X position is not within the layout, then
the start or the end of the line is chosen as described for
pango_layout_line_x_to_index(). If either the X or Y positions
were not inside the layout, then the function returns FALSE; on an
exact hit, it returns TRUE.
Parameters
| x | int | 
| the X offset (in Pango units) from the left edge of the layout. | |
| y | int | 
| the Y offset (in Pango units) from the top edge of the layout | |
| index_ | int* | 
| location to store calculated byte index | |
| Direction: out | |
| Ownership of the data is transferred to the callee | |
| trailing | int* | 
| location to store a integer indicating where in the grapheme the user clicked. It will either be zero, or the number of characters in the grapheme. 0 represents the leading edge of the grapheme. | |
| Direction: out | |
