Description

get_mbutton_sub_pixget_mbutton_sub_pixGetMbuttonSubPixGetMbuttonSubPixGetMbuttonSubPixget_mbutton_sub_pix returns the subpixel accurate image coordinates of the mouse pointer in the output window and the mouse button pressed. In addition the state of the modifier keys is returned. The following values are assigned to the individual buttons and keys:

1:

Left button,

2:

Middle button,

4:

Right button,

8:

Shift key,

16:

Ctrl key,

32:

Alt key.

The sum of the values for all pressed keys added to the value of the pressed mouse button is returned in ButtonButtonButtonButtonbuttonbutton.

The operator waits until a button is pressed in the output window. For graphics windows the coordinates RowRowRowRowrowrow and ColumnColumnColumnColumncolumncolumn are expressed with consideration of the current image part (see set_partset_partSetPartSetPartSetPartset_part).

If only pixel accurate image coordinates are required, you can use the operator get_mbuttonget_mbuttonGetMbuttonGetMbuttonGetMbuttonget_mbutton.

Attention

get_mbutton_sub_pixget_mbutton_sub_pixGetMbuttonSubPixGetMbuttonSubPixGetMbuttonSubPixget_mbutton_sub_pix only returns if a mouse button is pressed in the window.
