TabItems/TabPanels ignore my wishes...

Hi,

I cannot set TabItems invisible/disabled, nor do my events work...

The code:

Code:

---

tabFolder = new TabPanel<TabItem>();
        tabFolder.addListener(Events.SelectionChange,
                new Listener<BaseEvent>() {
                    public void handleEvent(BaseEvent tpe) {
                          // do something - but I never get here...
                    }
                });

[...]

        item = new TabItem();
        item.setText("Auswertung");
        item.addListener(Events.Click, new Listener<BaseEvent>() {
            public void handleEvent(BaseEvent be) {
                // do something - but I never get here...
            }

[...]
        item.setVisible(false);
        item.setEnabled(false);
        item.hide();

---

Nothing of this works... What am I doing wrong?

TabPanel fires a Select event on SelectionChange. Also, it passes a ComponentEvent, not a BaseEvent. You select tab items by calling setSelection on tab panel, not changing the visible state of the tab item. Take a look a the example code in the explorer demo.

I do not want to change the selected tab with 'setVisible' and 'setEnabled', I want to hide them (so the user is not able to select them).

But they remain visible, only the content seems grey (but is still working). The exact same coded worked, when I used myGWT - the tabs were hidden with setVisible(false) and got visible again when selecting setVisible(true) - but this doesn't work any more :(

Same with the Listeners - myGWT recognized when the user clicked on a tab (the event was fired) - but now, it's completely ignored...

I've come across this problem too, I can no longer hide tabs, here's an example...

Code:

---

import com.extjs.gxt.ui.client.widget.TabItem;
import com.extjs.gxt.ui.client.widget.TabPanel;
import com.extjs.gxt.ui.client.widget.Viewport;
import com.extjs.gxt.ui.client.widget.layout.FillLayout;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.ui.RootPanel;

public class SimpleTest implements EntryPoint {

    public void onModuleLoad() {
        Viewport viewport = new Viewport();
        viewport.setLayout(new FillLayout());

        TabPanel tabPanel = new TabPanel();

        TabItem tab1 = new TabItem();
        TabItem tab2 = new TabItem();

        tab1.setText("Tab 1");
        tab2.setText("Tab 2");
        tab2.setVisible(false);

        tabPanel.add(tab1);
        tabPanel.add(tab2);

        viewport.add(tabPanel);

        viewport.layout();
        RootPanel.get("slot1").add(viewport);

    }
}

---

tab2 should not be visible, but it is

I tried to implement a simple listener for when a tabitem closes:

(not a copy/paste, just from memory):

Code:

---


tabPanel.addListener(Events.Close,  new Listener<TabPanelEvent>() {
            public void handleEvent(TabPanelEvent te) {
                    dbService.unlockRecord(te.item.getRecord());
            }
});

---

but the event doesnt seem to fire (no errors). part of this issue? I figured it may be waiting for the tabPanel to close, instead of a tabitem... but why does te.item exist if thats the case?

Hi Darrell,

what's the latest news here? Do you understand my question and the confusing behaviour?

Is this an error in the library? Will it be fixed soon?

I will start a new GWT-project soon, and so I would be interested in the version I should use... mygwt or ext-gwt...

Thank you very much, your work is really appreciated!

Hi,

Hi

Can anyone tell me how to fire events on a TabPanel items.

I want to have a onTabSelected event in the TabPanel and also when the page loads fully i want to select the first tab item by which I want to fire an onTabselected event and make an RPC call to fetch the tab content.

Is this possible in MyGwt TabPanel..........Below is my code and I add this TabPanel to a contentPanel.I also tried a different approach by adding listeners to the TabPanel and the TabItems but i think it is not working out.
