I have a set of radio buttons that are placed within a box.
When the user selects an option, these buttons needs to be disabled. I cannot find a relevant property to disable all items within the box.Only option I can find is to set the hidden property.
box.isHidden=true
NSButton inherts from NSControl, which has an isEnabled property. If you want your radio buttons to still be visible but not clickable, use that.

By default ToolbarOptions contains copy, cut, paste, selectAll options. Can we add a custom action? For example, an action which will keep the selected text and remove unselected one.
It's currently not possible in flutter, you can only control show or don't show default actions by the toolbarOptions property of TextField.
There is a pull request on github to add this functionality but it's not fully done.
You can use Selectable to customize the toolbar options and assign actions upon press. You can also grab the selected text.

I have several radio buttons
I need to assign a radio group to it so that only one radio button is selectable at a time.There is no radio group option.I have tried
Assigning a single action outlet to all buttons
Putting all buttons in a custom view
None of this works.
In the old days, NSMatrix was the class that provided the radio group behavior. If you look up the docs for that class, you'll find the following note:
Use of NSMatrix is discouraged in apps that run in macOS 10.8 and later. If you need to create a radio button group in an app that runs in macOS 10.8 and later, create instances of NSButton that each specify a button type of NSRadioButton and specify the same action and the same superview for each button in the group.
So there are three things that all need to be true at the same time for this to work:
Your buttons all have to share the same superview.
Your buttons all have to have the same action.
Your buttons need to have their button type set to NSRadioButton.
I tried this out just now. I created a button in a view in my storyboard, set it's button type to "Radio" in the Attributes inspector, and assigned an action. Then I duplicated that button several times, and ran the app. The radio behavior worked automatically.
If it's not working for you, I'd start by doing what I did above. Just create a single radio button and set it up with an action. Then duplicate it a few times and test. If that works (it should), then either see if you can use that technique to get what you want, or look at what's different between what you want and what works.
I have a radio control with text package. I need to disable the control for the radio button. But the text should be enabled.
Can any one help?
The SWT radio button (new Button( parent, SWT.RADIO )) is a single control that can be enabled or disabled as a whole only.
Technically, you could use a separate radio button (without text) and a Label with a layout to position them side by side. Now you would be able to control their enablement separately.
However, radio buttons are a common and well-recognized UI elements that you would break by enabling/disabling the button and text differently.
When I want to know which radio buttons are selected in a panel in a MATLAB GUI, I use this line:
ChosenOption = get(handles.OptionPanel, 'SelectedObject');
where OptionPanel is the Tag of the panel where the radio buttons are located.
However, if I want to use checkboxes instead of radio buttons, is there any way to do the same?
Thank you.
You would typically get the Value property of each checkbox to determine whether it was checked or not.
Note that typically with checkboxes any, all, or none of the checkboxes may be selected (in contrast to radio buttons, where typically only a single radio button would be selected at any one time), so you would want to get the Value property of each checkbox separately. There's no equivalent of a uibuttongroup that you would use with radio buttons (although you can of course graphically group the checkboxes in a uipanel).
When I set up a custom button in Interface Builder it hides the Title text.
Do you have to create the text for the button too or is it possible to change the Z order so that the Title appears on top?
You are probably setting the 'Image' property of your button instead of the 'Background' property.
'Image' appears over your text, so either programmatically or in NIB(way simpler), set the 'Background' image to your desired png, and set the text for the desired button 'State Config'(default, selected etc), Leaving the 'Image' property blank.
The title by default appears on the top and in no case the text goes behind the button...
Still follow the below steps
1. Drag uibutton to the view
2. Select UIButton
3. Click on the first tab of the Inspector
4. Then Enter the title over there.
The title entered will be on the button..
Hope this helps
For a custom button, I fixed the same problem by going in interface builder and in the tab where you can set up hte title, image, background, etc., if you look lower, there will be a section titled "Control". In that section you can change the alignment and there are also some checkboxes for "Content". Put a checkmark in "Enabled" and "Selected" and it should work. Ensure to have populated the title for the various states of the button.
It may be related to the State Config attribute. I had the same problem and solved it by doing this:
Select your button
In the utilities pane (right pane), select the Attribute inspector (4th tab).
Change the State Config (2nd attribute) to the value "Default".
Enter a Title and press Enter (I tried changing it directly on the button but it is resized automatically).
You may switch back to your previous State Config if it is what you need.
