Abort loop on ProUIPushbutton

Hello,

I have to do some updates on instances of a big family table (ca. 1500 items).


In a synchrone application I create a ProUIDialog for special settings for the job,
and then I start the job clicking on an ProUIPushbutton.


Now, while the for-loop ist working, the dialog is not active and i can't press any body to abort?


What do I have to do to get these functionality to my application?


Any ideas?



Thanks for help!



Greetings Lars

Lars -

I think it's perfectly reasonable that you want to do this:

As far as I know, you need a multi-threaded application to do this,
something which Pro/Toolkit does not support. Here's a quote from
the Wildfire 4 Pro/Toolkit User Guide:

Although the library flags provide compatibility with
multithreaded components, Pro/TOOLKIT calls must be
made within a single thread. Pro/ENGINEER does not
respond to calls made from multiple threads.

Of course, I could be wrong about this. In fact, I would be
happy if someone could prove me wrong with a solution to your
problem.

Can anyone tell us that Lars is NOT a prisoner of single-threaded
programming?

Abort loop on ProUIPushbutton

Do you mean you would like to abort the dialog in the for looping when there
is some error?

ProUIDialog has a style named as PROUIDIALOGSTYLE_WORKING, which is set as
API *ProUIDialogDialogstyleSet().* Its introduction is as following:

A transient dialog type is used only to display some state information,
usually referring to the progress of some kind of lengthy operation =
PROUIDIALOGSTYLE_WORKING; This should be the value for dialogs with progress
bars.
My using is as following:
1. After you press the button of your dialog to do loop, the progress bar is
displayed with a button of CANCEL.
2. The progress bar will be updated when the loop going on.
3. If you press CANCEL button, close the progress bar and abort the loop.

RE: Abort loop on ProUIPushbutton

Hello,

thanks for the answers!


Have you tried that already?
That's what I've done, but it does not work.
I can't click the cancel button.


We are working on Wildfire 3.0.


Here an example:
The progressbardlg.res is in the Pro/ENGINEER text folder.


err = ProUIDialogCreate(DlgName, "progressbardlg");


err = ProUIPushbuttonActivateActionSet(DlgName, "ProgressBarStopButton", DlgCloseFunction, NULL);
err = ProUIDialogCloseActionSet(DlgName, DlgCloseFunction, NULL);


err = ProUIProgressbarMinintegerSet(DlgName, "ProgressBarDlgMeter", 0);
err = ProUIProgressbarMaxintegerSet(DlgName, "ProgressBarDlgMeter", 10);


err = ProUIDialogAboveactivewindowSet(DlgName, PRO_B_TRUE);
err = ProUIDialogDialogstyleSet(DlgName, PROUIDIALOGSTYLE_WORKING);
err = ProUIDialogActivate(DlgName, NULL);


for (int i = 0; i <= 10; i++)
{
err = ProUIProgressbarIntegerSet(DlgName, "ProgressBarDlgMeter", i);
Sleep(200);
}



void DlgCloseFunction(char *Dialog, char *Control, ProAppData Daten)
{
ProUIDialogDestroy(Dialog);
}

Abort loop on ProUIPushbutton

Hello,

1. The progress bar is created with API ProUIDialogCreate() before the loop.

2. Use API ProUIPushbuttonActivateActionSet() to set the call back
function for your stop button. The call back function will record
whether the button is pressed, and set its value to a bool variable.

3. At the beginning of each loop, check whether the bool variable (got
from step 2) is set to stop the loop.

4. API ProUIProgressbarIntegerSet() is used in the loop, which means
the progress bar will be updated for each loop. After this API, you
also need to call API ProUIDialogActivate() to activate the progress
bar dialog.

5. API ProUIDialogDestroy() is called to destroy the dialog after the loop.

RE: Abort loop on ProUIPushbutton

Hello,

I think that's what I did! Isn't it?

But while the loop ist running it is not possible to click the stop button!


Thanks!

Abort loop on ProUIPushbutton

Please see the step 3:

3. API ProUIProgressbarIntegerSet() is used in the loop, which means
the progress bar will be updated for each loop. After this API, you
also need to call API ProUIDialogActivate() to activate the progress
bar dialog.

API ProUIDialogActivate() should be called to activate the progress
bar dialog every loop. If the dialog is not activated, I think it
cannot be picked with the button. In your code, I did not see it.

In your code, there is no stop action for the loop after the stop
action from progress bar. Therefore, the dialog is only destroyed
after the loop finished.

I am not sure whether Sleep() will have affect for this.
