Hi
Im trying to using controlpanel such as button and popupmenu. My datas uploaded from LabVIEW wich another program. I define different button for different requirement but unfortunately when I press those buttons, they work only one time, my goal is after press one button, only this part works continuously.
My questions:
1.Is there any way that my program work in better way? I mean when I press one button, the code works in that part until I press another button?
2. About poupmenu, how can I travel between different option? For example in my attachment, in one of my popupmenu there are tree option(Bin, ROI, Main), do I need define different function for them?
3. In part of binning and ROI, they upload in different graph. can somebody please tell me how can I see this guys in same graph as wave0, so I want to press button of RoI and it appears in my previous graph and if I press binning it also appears in same graph. Now I have those in different graph and I like to substitute them.

Thanks

Pressing a button will cause the function linked to it to execute. If you wish it to "disable" other features you must add that code in yourself. This can be done using a controls 'disable' property. If this isn't what you meant could you elaborate?

The popupmenu change will pass it's current value to the function linked to it (the proc). Based on this value, you can then decide which code to run. One function, with either a case structure of nested if-elseif-endif statements.

The key aspect of this question is "How will the code identify the graph it's supposed to add the ROI or binned data to?" Basic commands like AppendtoGraph will add to the topmost graph, whichever that may be unless they are provided with the windowname getting the window name of the proper graph will be important. One easy way to do this is to have your panel actually create the graph initially with a known windowname that you can use throughout the code. There are other methods of getting a window's name but I find it simpler to create a known one.

You right but for example I have this code:

Button button0_tab0,pos={60,310},size={161,35},proc=ROIProc,title=" ROI"
Function ROIProc(ROIName) : PopupMenuControl
String ROIName
wave Atomparameters0
print (1,2,3,4,5)
I want it print me until I press button again. Unfortunately it print one time not more, is it possible that it works more time with only one press?

May you please write one example about the popupmenu change, I didn't get your reply for question 2.

It sounds like what you want could be accomplished by simply writing an infinite loop in a user-defined function. But that won't work because control action procedures won't be called while such a loop is running. You really need a background task. The Igor help has an example of what I think is exactly what you want:

DisplayHelpTopic "Background Task Example #2"

You should read all about background tasks:

DisplayHelpTopic "Background Tasks"


Here's a quick example of a popupMenu control. Execute Panel0() to display the panel:
Window Panel0() : Panel
    PauseUpdate; Silent 1       // building window...
    NewPanel /W=(150,50,450,250)
    PopupMenu popup0,pos={107,72},size={67,20},proc=PopMenuProc
    PopupMenu popup0,mode=2,popvalue="Yellow",value= #"\"Red;Yellow;Blue;\""
EndMacro

// The action procedure for the popupMenu control:
Function PopMenuProc(pa) : PopupMenuControl
    STRUCT WMPopupAction &pa

    switch( pa.eventCode )
        case 2: // mouse up
            Variable popNum = pa.popNum
            String popStr = pa.popStr
            print "You selected item #"+num2str(popNum)
            print "That item has the text \""+popStr+"\""
            StrSwitch(popStr)
                case "Red":
                    print "Do something with Red"
                    break;
                case "Yellow":
                    print "Do something with Yellow"
                    break;
                case "Blue":
                    print "Do something with Blue"
                    break;
            endswitch
            break
    endswitch

    return 0
End

Thanks.
I wrote this code but it doesn't execute. Do I need to do some thing that this part runing?

It seems you forgot the proc=PopMenuProc flag in you popup control code, which tells the popup menu the function name to use for execution.

Sorry, I forget put here but infact I put in my main code.
you can see in my attachment, I walk in different case of Popmenu but nothing is changes.
Do you have another suggestion please?

It's hard to debug a picture of code. And "it doesn't execute" doesn't tell us much. Do you really mean that nothing happens? Do you see your print statements printing into the history window?

Perhaps you should post the entire experiment file.

Hi Johnweeks,
can I ask a request?
Thanks for your program, now this part of my code is work:
Window Panel0() : Panel
PauseUpdate; Silent 1
NewPanel /W=(150,50,450,250)
PopupMenu popup0,pos={107,72},size={67,20},proc=PopMenuProc
PopupMenu popup0,mode=2,popvalue="Image",value= #"\"Image;Binning;ROI;\""
EndMacro

Function PopMenuProc(pa) : PopupMenuControl
STRUCT WMPopupAction &pa

switch( pa.eventCode )
case 2: // mouse up
Variable popNum = pa.popNum
String popStr = pa.popStr
print "You selected item #"+num2str(popNum)
print "That item has the text \""+popStr+"\""
StrSwitch(popStr)
case "Binning":
imageinterpolate/pxsz={2,2} pixelate wave0
Display /N=new
AppendImage M_PixelatedImage
SetAxis/A/R left
ModifyImage M_PixelatedImage ctab= {*,*,Rainbow,0}
break;
case "Image":
print "Image"
break;
case "ROI":
Duplicate/O/R=[10,50][200,300] wave0,roi
Display /N=ROI
AppendImage roi
ModifyImage roi ctab= {*,*,Rainbow,0}
SetAxis/A/R left
break;
endswitch
break
endswitch

return 0
End

Now I want to run periodically this cod so as you told I need use Background Tasks then I put this code in example 2 but I could not do. May you please send me example with my code?
