Comments on: Panel-level uicontrols

Garuve, one easy way to put a control on top of a panel simply put the panel as the parent.

exampleFigure = figure;
hp = uipanel('Title','Main Panel','FontSize',12,...
             'BackgroundColor','white',...
             'Position',[.25 .1 .67 .67],...
             'Units', 'Normalized');
cb = uicontrol(hp,'style','checkbox','position',[100,100, 20,20])

@Yair: Could you provide an example of doing this (in HG2)? I can’t get it to work (i.e. I don’t know how to put a checkbox uicontrol ‘on top of’ the panel?
Very much appreciated!

@Kusi - no: in HG2 (R2014b) the Matlab uipanel is (finally!) implemented as a true Java Swing component (deriving from JPanel), and the title is implemented as a standard Java titled-border. In other words, it is no longer a separate uicontrol.Instead, you can simply place a dedicated checkbox uicontrol on top of the panel, you just need to ensure the position is correct and normalized so that it moves with the panel when it changes its size/position.

In R2014b, it seems like the TitleHandle property is gone. Is there another way to have panel-level check boxes?

@Patrick – just do as I suggested, read the link I provided.

Hello Mr. Altman,
i don’t understand. It’s from your own post here.

@Patrick – you used javacomponent incorrectly. Read about the correct usage here: https://undocumentedmatlab.com/blog/javacomponent

Hello Mr. Altman,
I don’t know where exactly to ask, so I ask here.
I found in the internet one respond from you

[jPanel,hPanel] = javacomponent(javax.swing.JPanel);
set(hPanel, 'units','normalized','position',[.1,.1,.8,.8]);
hControl = uicontrol('style','pushbutton', 'parent',hPanel, 'string','click me');

I have tried this code with Matlab 2013b and the Panel is empty somehow. I don’t know why.
But my question IS… I want to add an undetermined amount of editboxes and labels to a panel. It can be 1 or 32 or even more.
I don’t want to resize them according to the space because then they would be extremely too small. So i need a Scrollbar.

I thought to use a JPanel and put it in a JScrollpane, but i failed at the first step up there. The jPanel is empty.
Do you know what’s wrong?

greetings

@Ninad - you can try to use property-change listeners.

Can i add callback on any property change of matlab uipanel or uicontrol?

[…] Notice that the panel names are still missing. So far no solution for this has been found. Perhaps this can be overcome using the fact that uipanel titles are simply hidden children of the panel object. […]

I looked at jTabGroup using

uiinspect(jTabGroup)

is there a property to make the separator line appear?

By: Alex

Alex — Wed, 01 Dec 2010 10:40:32 +0000

Is it in the schema.m? I tried to modify the line

jpanel = javax.swing.JPanel(java.awt.BorderLayout);
[comp2, h.HgContainer] = javacomponent(jpanel,[1 1 1 1], h.parent);

but I couldn’t see the effect.
I’m new to Java, so could you please give me more hints?

Alex - Matlab uicontrols and axes cannot be added to Java containers (well, at least not without a herculean effort).This is why MathWorks implemented uitab so that uicontrols/axes are not added directly to the tabs but rather to invisible Matlab containers that are handled by the tab callbacks.Under the hood, uitab is a simple JTabbedPane that has no containers, only tabs. So, fixing it such that the missing separator line appears should be a simple enough exercise for you.Please post the necessary changes to the uitab.m file (or its relatives) here if and when you succeed.

Thanks, that’s exactly what I was looking for. Can you give ma an example how to add a Matlab uicontrol and axes to a tab? Can I set the ‘parent’ property to an uicontrol or is there another way now?

Alex – The uitab control (explained here, with additional articles earlier this month that showed how to customize the tab appearance and behavior), hides the separator line in its internal implementation. In the example on this page I used a Java JTabbedPane directly, and this preserves the separator line. Here’s a simple example:

[jTabbedPane, hContainer] = javacomponent('javax.swing.JTabbedPane', [20,50,200,200], gcf);
jTabbedPane.addTab('tab #1',javax.swing.JPanel);
jTabbedPane.addTab('tab #2',javax.swing.JPanel);

In the first image in this article, how did you achieve the horizontal line under the tabs that are not active?
