Force a screen refresh?

Merf689

I have a skill routine that searches for a given set of instances and will replace those instance automatically.  The GUI has (I'm hacking another user's skill) two buttons,

a "find next" button and a "replace" button.  I've combined the functions into a single button that's a "replace then get next" function that's a simple call of the two functions

used in the two-button approach.  I'd like the system to simply wait 1-2 seconds before going to the "next" instance.  I've put the callbacks in the proper order and everything 

works correctly EXCEPT, a screen refresh doesn't happen that'll allow me to quickly review the replacement.  I've tried using various implementations of "sleep" and hiRegTimer

but can't seem to get anything to work.  Code snippet below:

;Merf's replace+next function
323 procedure(mdrReplaceViaNextCB(hButton hForm)
324 printf("KM-Replacing...\n")
325 mdrReplaceViaCB(hButton hForm)
326 hiRedraw()
327 printf("Waiting... \n")
328 hiRegTimer(mdrShowNextViaInstanceCB(hForm) 100)
329 ;mdrShowNextViaInstanceCB(hForm)
330 printf("Done!\n")
331 );

The code will make the substitution and wait 10 seconds before moving on but the screen doesn't update... what am I missing?

  • It's hard to know for sure without seeing more of the code, but at least the first argument to hiRegTimer() is wrong in your case. It needs to be in quotation marks as otherwise it will be evaluated immediately (and probably fail when it eventually gets that far):

    hiRegTimer("mdrShowNextViaInstanceCB(hForm)" 100)

    Note however, the hForm would need to be a global variable - because the expression is going to be evaluated in the global scope - so whatever the form is called. Or you'd have to find that out and construct the right expression with sprintf.

    If you get stuck, I suggest you contact customer support because then we could take a look without you having to share the full code in a public forum.

    Regards,

    Andrew.

  • Thanks Andrew, I'll give this a look...

  • Hi Merf!

    I'm wondering if maybe you need to explicitly tell hiRedraw() which window to redraw.  The manual says without an argument it uses the current window.  I've noted currentWindow() and hiGetCurrentWindow() give different results so I'm really not sure which window you're redrawing in this case.  I figure being explicit never hurts.  I have an ugly bit of example code that works.  As Andrew noted though the hiRegTimer needs to look more like:

    hiRegTimer("mdrShowNextViaInstanceCB(hForm)" 100)

    but that has issues due to variable scoping.  You may be able to do something like

    sprintf(cmd "mdrShowNextViaInstanceCB(%L)"  hForm->hiFormSym)

    hiRegTimer(cmd 100)

    Cheers
