App Designer Tab Groups

Hi,

I am trying to make an app with multiple tabs and I am experiencing some difficulty. How do you turn Tabs on and off in app designer? I attempted using the following code:

               app.Tab.HandleVisibility='off';

However, nothing happened. The tab still appears when I run the code.

Thanks,

April

Ich it possible to add to an existing app a tabgroup in the way, that the original ap is (unchanged) on the first tab?

I'm not quite sure what you're asking. Consider asking a new question since the topic appears to differ from this thread.

Answer 1

An alternative is to keep the tabs visible but prevent the user from selecting them under certain conditions.

This demo uses checkbox values to control whether a tab can be selected or not.

Hi, is it possible to customize the appearence of the tabs, I mean, the heigth and width and the distrubution in the whole tab bar?

[Adam Danz]

The postion property of Tabs is read-only which prevents changing width or height of Tabs. Tab order can be changed but not spacing between tabs.

Another way of doing it:

• Create a dummy

tg = matlab.ui.container.TabGroup;

• Suppose your tab is in index 2, then do

app.TabGroup.Children(2).Parent = tg;

• After this the tab is not visible anymore

• To make it visible again do the opposite

tg.Children(1).Parent = app.TabGroup;

• The only remaining action is to permute the children of app.TabGroup so that the last Children goes back to index 2, and voila, visible again in the right order!

You might have to change the property name TabGroup to the one in your application if it is not the default Property name.

Awesome!

Could you tell me pls how i can disable different Tabs by default?

I try to activate different tabs from a tab group by checkbox.

[Jorge Paloschi]

Create a dummy TabGroup and parent in that tab group all the tabs that you want disabled. Then as you click on the check box to enable a tab, you move the respective tab from the dummy to your gui (in the right position), and viceversa if you want it disabled.

have you got succeed ? if yes, can I see your code please ?

[Vijay KG]

@jorge paloschi: with a single tab, your solution was able to hide the tab. but if i have multiple tab, not able to fix it. could you please help on multiple tabs? Thanks.

Thanks.

This is way harder than it should be. Why isn't there a Visibility property?

[Michael]

^^^ Exactly this - why is it so difficult? Have Enable and Visibility properties for tabs in groups!

If you want to show and hide the tabs as the user interacts with your app, one way to do this is to add a second TabGroup and set its visibility to off. When you want to hide a tab, set it's parent to the second, hidden tab group, app.Tab.Parent = app.TabGroup2. When you want to show it again, set it back to the visible tab group, app.Tab.Parent = app.TabGroup.

[Dominik Müller]

Okay this is a way to show / hide tabs. But if I do so and switch between the tabs all items on the tab are hidden. What am I doing wrong? And how to fix this?

If you want to change which tab in a group is visible, you can use:

app.TabGroup.SelectedTab = app.Tab1

where Tab1 is a tab in the group.

If you want the entire tab group to disappear from the screen, you can use:

app.TabGroup.Visible = 'off'

Hi Liz,

Thank for your response. I have two tabs in my program. I tried the following solution to make just one of them visible:

app.TabGroup.Visible='off' app.TabGroup.SelectedTab=app.Tab1

According to the previous response, this should turn both tabs off and then make the first tab visible. However, both tabs remain turned off. The only way I can make them possible is to change app.TabGroup.Visible to 'on'. However, then both tabs appear. Is there a way to fix this?

Thanks

April
