Dialog box which block current execution

[Joseph_BERTHE]

Hi,

I'm looking for a solution which show me up a pop-up dialog box, and after the creation of this, it will block the execution of my main code until the user click on the OK button into the popup dialog box.

I try to use modal window, but it doesn't block the execution.

e.g.

CODE A

CREATION DIALOG BOX

SHOW DIALOG BOX

CODE B

when the dialog is shown, then the code B is executed only if we destroy the dialog box.

Thanks

Hi,

Thanks for your links, but I'm using WD for Java. Furthermore, I don't get the relation with dialog box.

Berthe,

If you are using WD for Java then:

1. Use IWDWindowManager (wdComponentAPI.getWindowManager()) to create confirmation dialog.

2. In some action handler run code A, then open confirmation dialog

3. In event handler for button in confirmation dialog place code B.

Hi Valery,

Thanks for your answer. It is the solution that I'm using and it works fine.

But I'm wondering if there was others suitable solutions.

Thanks anyway

Berthe,

Unfortunately, there are no simplier solution with WD. In some other Java web frameworks like Cocoon (with Javaflow support, Java) or RIFE (Java) or Seaside (Smalltak) you may use continuations. So you can write liniear code in for:

List modifiedRecords = getModifiedRecords();
boolean confirmUpdate = queryUserAndWait("Modify records?", modifiedRecords);
if (confirmUpdate) 
  updateRecords(modifiedRecords);

In aforementioned frameworks thread state is serialized and response is sent back to user when queryUserAndWait method invoked. After user submits answer, frameworks restore erxecution state of thread and resume (continue, hence continuations) execution right after queryUserAndWait method return.

Again, in WD you have to emulate this behavior with separate action/event handlers.

Hi,

Sorry but I don't understand your solution :(. It sounds good, but I don't get it.

Otherwise, I don't understand an other thing. I've made this code but it desn't work at all:

IWDWindowInfo windowInfo = (IWDWindowInfo) wdComponentAPI.getComponentInfo().findInWindows("ScheduleLinesChoiceBox");

IWDWindow window = wdComponentAPI.getWindowManager().createWindow(windowInfo, true);

window.setWindowPosition(WDWindowPos.CENTER);
window.setTitle("ATP Control");
window.open();

wdContext.currentContextElement().setScheduleLinesPossibleWindow(window);
wdContext.currentContextElement().setWait(true);
	
while(wdContext.currentContextElement().getWait());

With your framework, how can I implement it with this requirement ?

There is my requirement :

do

...

some instructions

...

Ask to my client something (pop-up/confirmation)

if (yes)

do something

else

do something

...

next customer

while (customer != null)

Berthe,

Sorry for confusing you, it was just a rant that something like you whant is available in <b>other web frameworks, not in WebDynpro</b>

VS

Hi Valery,

Thanks anyway.

But for the future of WebDynpro, it should be interresting to have a such dialog box.

Kind regards,
