Help with send command

[phaworth]

I have a button on card A which when clicked should use the send command to send a mouseUp event to a button on card B. I've done this by issuing the send command followed by a go command.

If card B is already open, this works fine. If card B has not yet been opened in the current run of the application, it doesn't open. If card B has been opened at least once during the current run but then closed again, this works.

The code looks like this:

Code: Select all

send "mouseUp mySQL" to button "triggerFilterButton" of card "DB_Places" of stack "Places"
go  stack "Places"

I've also tied using the go command to a the card within the stack (there'sonly one crd in the stack). I've tried issuing the go command before the send command - same problem

ANy ideas?

Thanks,
Pete

Hello,

I think that the problem might be in your script... try

Code: Select all

send "mouseUp" to button "triggerFilterButton" of card "DB_Places" of stack "Places"
go  stack "Places"

without having MySQL behind 'mouseUp'

I have just created a stack which has two cards named, 'A' and 'B'... On each card there is a button named 'A' and 'B' respectively. In the script of button 'A' on card 'A', I placed

Code: Select all

on mouseUp
   send "mouseUp" to button "B" of card "B"
   go card "B"
end mouseUp

In the script of button 'B' of card 'B", I placed

Code: Select all

on mouseUp
   put "This is a message from button B on card B"
end mouseUp

Rev goes to card 'B' and the response appears in the message box every time... it does not matter if it is run on opening the stack or if the stack has been opened and the cards have been visited...

be well

Thanks for the suggestion. I tried it without passing the mySQL parameter but still getting the same problem. Useful to try but it turns out I have to pass in the mySQL parameter for the logic of my app to work, unless I can find another way to hand mySQL off to the button in question.

Pete,
if you want to send a parameter with your command you could put a comand in the receiving button "triggerFilterButton" like this:

Code: Select all

on triggerMyFilter tMySQL
       put tMySQL into field 1
   -- do whatever you want with tMySql
end triggerMyFilter

in the sending stack you put

Code: Select all

on mouseUp
   put "this is a test" into tParameter
   send triggerMyFilter && tParameter to btn "triggerFilterButton" of card 1 of stack "Places"
end mouseUp

Probably your button "triggerFilterButton" has a routine to work on mySQL, you could break that out in the button to let the "triggerMyFilter" handle it. The tMySQL would be passed from the mouseUp handler along with the command.
or you could use a global variable to make mySQL accessible to your receiving button, but I don't like global variables, it is easy to loose track of what handler fills them and when.

Thanks Bernd. I've been working on this today and have put what used to be in the mySQL variable into a custom property of the target of the send command. That all works well but I still have the same issue with the from not opening.

If it sheds any further light on this, when I do this in the standalone app version of my application, I get the error dialog box and the details supplied in the Email option are:

Executing at 10:48:08 AM on Sunday, February 7, 2010
Type: Handler: error in statement
Object: group 'PlacesGrid' of group 'DB_Places' of card 'DB_Places' of stack 'Places' of stack '/Applications/BandTrak/BandTrak.app/Contents/MacOS/BandTrak'
Line:
Line Num: 0
Hint: -8

One thing I would like to do is somehow trace all the vents that occur after I click on the original button that sets this whole process in motion. Is there a way to trace events in the debug tool?

Thanks,
Pete

Hi Pete, Dixie and Bernd,

you CAN pass a (string) parameter to "mouseup", I am doing this in our current project successfully!

"Normally" you only pass a number (the mousebutton actually clicked 1, 2 or 3) but you can also pass a string if necessary:

Code: Select all

on mouseup tParam
  put tParam into fld "whatever"
  ### more mouseup stuff here...
end mouseup

Sorry, no idea about the other problems you have.

Best

Pete,
in the IDE you can use the Message Watcher in the Development Menu. It lists, well, the messages.
I don't know if this helps.
@ Klaus, good to know, I thought it was always the the mouseButtonNumber that were passed to mouseUp

Hi Bernd,

well, this is USUALLY the case.
But I simply tried it, it worked, so I use it when needed

[phaworth]

Thanks for all the advice, I think I've fixed the problem now. There was some code that was being executed in the openCard handler of "card B" that I think was causing problems with the execution of the code I was sending the mouseUp message to. I still don;t fully understand exactly what was going on but after fixing that issue, all seems to be working well now.

If you're using glx2 then you should have that info available. The IDE's error reporting is fairly terse about this. But if you want to handle the errorDialog message yourself then you can print out the executionContexts, which will give you the call stack, both in the IDE and in a standalone.
