 |
|
The following code demonstrates an unexpected problem I came across yesterday when adding %th help messages to a window that also has a %dl timer.
If the same window uses %th and %dl, when the user places (and keeps) the mouse over the control with the %th, the displayed help will appear and then disappear at the next instant the %dl call back is run.
I wonder if the %dl call back should be inhibited internally by Clearwin+ when %th is displaying a help message? Reason - the program is not idle (i.e. awaiting input) since it is displaying a help message.

implicit none
integer :: k = 1

integer function increment_cb()
k = k + 1
increment_cb = 1
end function increment_cb
integer function gui2()
integer, save :: iw
iw = winio@('%mn[Exit]&','exit')
iw = winio@('%th[delay]&', 1, 500)
iw = winio@('Value of K%ta%`8rd%ta%^?bt[INC][Add 1 to K]&', k, increment_cb)
iw = winio@('%dl',5.d0,do_something_cb)
gui2 = 2
end function gui2
integer function do_something_cb()
print*, '%dl call back'
do_something_cb = 2
end function do_something_cb
end module test
program main
use test
i = gui2()
end program main |

This is an interesting problem.
I wonder if, because of the %dl callback, the underlying window would have a "FOCUS_LOST" event occur? That would explain the help text disappearing. |

I will take a look at this.
The quick fix is to add %th[ms_style]. |

Paul,
No need to looked at this, I missed the [no_callback_hide] option when reading the documentation.
