Arguments

dst_x_coord_return

UNGRAB BUTTON

OpenVMS Format

X$UNGRAB_BUTTON

(display, button, modifiers, window_id)

Argument Information
Argument Usage Data Type Access Mechanism
display identifier uns longword read reference
button longword longword read reference
modifiers mask_longword uns longword read reference
window_id identifier uns longword read reference

Arguments

button

The button on the pointing device that is no longer grabbed. The possible values are as follows:
X$C_BUTTON1
X$C_BUTTON2
X$C_BUTTON3
X$C_BUTTON4
X$C_BUTTON5
X$C_ANY_BUTTON

The predefined value X$C_ANY_BUTTON or AnyButton can be specified to allow any pointer button to be released.

modifiers

A bit mask that specifies the set of key masks associated with the button grab. This mask is the inclusive OR of these key mask bits:
Bit Predefined Value
1 X$M_SHIFT
2 X$M_CAPS_LOCK
3 X$M_CONTROL
4 X$M_MOD1
5 X$M_MOD2
6 X$M_MOD3
7 X$M_MOD4
8 X$M_MOD5

Clients can also pass the X$_ANY_MODIFIER constants, which is equivalent to issuing the ungrab request for all possible modifier combinations (including the combination of no modifiers).

(display, keycode, modifiers, window_id)

Argument Information
Argument Usage Data Type Access Mechanism

4 X$M_MOD1
5 X$M_MOD2
6 X$M_MOD3
7 X$M_MOD4
8 X$M_MOD5

Clients can also pass the X$_ANY_MODIFIER constants, which is equivalent to issuing the ungrab request for all possible modifier combinations (including the combination of no modifiers).
