Method
PangoLayoutxy_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. | |
| The argument will be set by the function. | |
| 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. | |
| The argument will be set by the function. |
