Open a maximized form from the outline [message #1867002]

Hello,

Is it possible to directly open a form in maximized modewhen I click on a page in the outline?

For example, in the BSI widgets, you have the CalendarFieldForm. Can it be directly opened in a maximized state when clicking on the outline?

I would like to get rid of the header/menu for this form only and have more space on screen

There is not a single property for this. Instead, some parts of the desktop can be hidden individually:

    IDesktop desktop = IDesktop.CURRENT.get();
    desktop.setNavigationVisible(false);
    desktop.setNavigationHandleVisible(false);
    desktop.setHeaderVisible(false);

You can test this here: https://scout.bsiag.com/widgets/?dl=widget-desktop

Is this the only form in your application? If yes, you can try to set the property "displayStyle" of the desktop to DISPLAY_STYLE_BENCH. Otherwise, you could add a "fullscreen menu" to your form, or run this code on the page activate event. But make sure you provide a way to make the hidden elements visible again, otherwise the user would not be able to select other pages anymore.

Thank you for your response. However, I would prefer not to manage the visibility of the header myself, which is why I would rather implement something that works like a simple form.

Just like something I can execute from a button:

MyForm form = new MyForm();
form.setMaximized(true);
form.setModal(true);
form.setDisplayHint(DISPLAY_HINT_DIALOG);
form.setClosable(true);
form.start();

I would like to execute this same code when clicking on a page in the outline.
then when closing the form -> back to the outline menu.

I am asking this to have more usable space on the phone when looking at a calendar form. The desktop.setHeaderVisible(false); does not seem to work on phone anyway.

is it possible?

Easy. Run your code when the page is activated:

public class MyPage extends AbstractPageWithNodes {
  @Override
  protected String getConfiguredTitle() {
    return TEXTS.get("MyPage");
  }

  @Override
  protected boolean getConfiguredLeaf() {
    return true;
  }

  @Override
  protected void execPageActivated() {
    MyForm form = new MyForm();
    form.setMaximized(true);
    form.setModal(true);
    form.setDisplayHint(DISPLAY_HINT_DIALOG);
    form.setClosable(true);
    form.start();
  }
}

You might also want to provide a detail form that has a "reopen" button to allow the user to open MyForm again without first selecting a different page and coming back.

I have already tried something similar but I could not find a way to also close the "MyPage" so that when an user close the form, he goes back main page where he sees all the pages in the outline?
I have tried to dispose the page when closing the form, but was not successful, maybe somthing I did not understood with the page lifecycle.
It could simplify the process and avoid this "reopen" button.

I would like to use something like that

Desktop.get().activateOutline(Desktop.get().getAvailableOutlines().get(0));

myPage.dispose()

in the execDisposeForm() method of the form but no success.

Also tried to trigger the back button in the page (the one which shorcut is backspace)

Note : If I try

Desktop.get().activateOutline(Desktop.get().getAvailableOutlines().get(1));

It works and open the second outline, but since the page is in the first outline, It seems I cannot display it

Finally solved it using

Desktop.get().getOutline().resetOutline(false);

I see. You are (ab)using the outline tree as a kind of menu system. This is not really its indended purpose, but nevertheless it should be possible to achieve the desired effect.

The outline as just a special tree widget and a page is just a special tree node. execPageActivated() gets called when the tree node is about to be selected. So opening the form at this point is correct. What remains is jumping back to the previously selected node. This can be done by programmatically selecting a different tree node. Because during execPageActivated(), the new node is not yet selected internally, we have to wrap this call in a separate model job.

public class MyPage extends AbstractPageWithNodes {
  @Override
  protected String getConfiguredTitle() {
    return TEXTS.get("MyPage");
  }

  @Override
  protected boolean getConfiguredLeaf() {
    return true;
  }

  @Override
  protected void execPageActivated() {
    // Open form
    MyForm form = new MyForm();
    form.setMaximized(true);
    form.setModal(true);
    form.setDisplayHint(DISPLAY_HINT_DIALOG);
    form.setClosable(true);
    form.start();

    // Deselect page
    ModelJobs.schedule(() -> {
      getOutline().deselectNode(this); // or: getOutline().selectNode(this.getParentNode());
    }, ModelJobs.newInput(ClientRunContexts.copyCurrent()));
  }
}

I was able to achieve this by using

Desktop.get().getOutline().resetOutline(false);

in my execDisposeForm method. Thank you very much for the additional details; they were very helpful.
