Is there a way to select several buttons inside a formLayout (or any other layout) with a drag selection?
Like how you would do with maya objects in viewport, but inside a custom MEL UI
i know you can use getModifiers to know if Shift is pressed to not and thus mimick shift selection etc
but drag/marquee selection seems, very hard, to replicate...
I don't think you can use Maya's standard interface objects to achieve that, but yes, you can absolutely do it with PySide in Python.
Check out examples for QtWidgets.QGraphicsView and QtWidgets.QGraphicsScene. Their framework is setup so that you can create items inside their view, and be able to select multiple with a marquee. They can also support moving via dragging the items, so you can even go as far as having a body picker creator without having to hard-code it. You could even be fancy as to create path items with beziers handles (like Photoshop) so that the user can create their own custom shapes, though you would have to manually make that framework.

I am trying to build a form with a phone input that includes country codes. Essentially, I am trying to make something a lot like this:
I already found and cleaned a list of flags, countries, and their codes, and built the method that creates a DropdownMenuItem for an arbitrary index. I then construct a list of them and pass it to the DropdownButton widget. It's all very simple, so I don't think the code is necessary. However, because I have so many countries, and therefore menu items, the menu lags significantly when opening. So, I was wondering if drop down menus are capable of loading large numbers of widgets in a smarter fashion than it seems they do.
Can a drop down menu could load the first 10 or so widgets around the selected index and display them, as that is all that will be in view initially, and then load the rest of the widgets asynchronously? I suspect that this will require a custom drop down menu, but I am not very well versed in the implementation of Flutter's drop down menu, so I am unsure of how to proceed with this.
Any help is appreciated.
I don't think that "loading" is the actual problem here, more likely it's the rendering/building of the widgets. You can improve the situation by using something like a ListView.builder that builds items on demand.
It seems like the default dropdown system is not based on a ListView.
You can create your own version of the dropdown (like a complete customized copy of the classes), which will require quite quite a lot of work and research.
Or alternatively, use something like a SimpleDialog with an embedded ListView to display the list. Like this one for Android.
I need to implement a threaded view of sorts in an old VB6 app. It should look similar to this:
So, it's like a TreeView of sorts but there are buttons on the right (for each row) that could be pressed. The view does not need to collapse - it always stays in the expanded mode. The users should be able to respond to each node (via the comment button on the far right). And, of course, users should be able to scroll through the entries.
What are some of the ways I could implement this? I am open to 3rd party controls, paid or not.
VSFlexGrid has an outline mode. You can set the indent per row via the RowOutlineLevel property. It supports word wrap, images, etc within its cells/columns so you should be able to get pretty close to what you want. It also supports owner-drawn which lets you fully customize the cell painting (for example, to get those rounded corners).
I'm sure there are other controls out there as well...
Is it somehow possible to insert an EditorArea into a View in Eclipse RCP?
I would like to define a restricted area, inside of which the Editors may be moved.
Not easily - in general, there is 'one' EditorArea for an Eclipse application.
You could use a custom presentation layer to put that EditorArea over one of your views, but that would be it.
A potential (high-level) solution would likely involve passing an EditorPart instance to a custom view, which will then call createPartControl to render the editor contents inside the view, and manage any necessary initialization of the editor.
Since this editor would be a child control of the view, you might also need to do special hookups for selection/editorsite/actionbars/shortcut keys, etc, so that they continue to work when that editor is being run from within the view.
I'm building an application to generate an array of colors based on a color chosen by the user.
The default on Mac OS X for color selection is to open a NSColorPanel containing multiple NSColorPickers. But, as the color selection process is the main interaction the user will have with the app, it'd be better to avoid the extra clicks and panel-popping in favor of a more straightforward way.
So, is there any way to add a NSColorPicker object to a window?
I know this is an older question, but check out NSColorWell. From the docs:
NSColorWell is an NSControl for selecting and displaying a single color value.
Interresting Question.
I strongly doubt it (but would love to be proven wrong). NSColorPickers are not NSControls (nor NSCells) so there's no clean wrapper to insert into a window.
Even if you were to instanciate an NSColorPanel and get a reference to its contentView and copy it (with all that defines the color picking controls) to your own window... there's no obvious way of obtaining the color value. NSColorPickers are plug-ins so you can't forsee the controls of a colorPicker.
The only other way I can see (and that's a stretch) would be to manually load the NSColorPickers plug-ins directly. I don't know how successfull this would be.
File a bug report and request the feature?
Does anyone have an example of using a QWidget as an editor in a QAbstractTableModel?
I have a column which when edited should create a QCombobox with the list of choices.
The docs seem to suggest I need to write a QAbstractItemDelegate and a custom paint function but that seems overkill to simply pop-up a standard QCombobox in Qt::EditRole.
Note - the combo box contents are the same for every row and it only needs to be shown when somebody clicks in the cell.
I know this should be simple but I can't get it to work. It's easy for a QTableWidget based table - but I need it for a very large data table.
The docs seem to suggest I need to write a QAbstractItemDelegate and a custom paint function but that seems overkill to simply pop-up a standard QCombobox in Qt::EditRole.
You don't need to go that far. One way is to subclass QStyledItemDelegate and then override createEditor() so that it returns your prepopulated combo box. Its setEditorData and setModelData functions will probably already suffice if you`re using basic Qt value types.
If you need something more generic that works across many different models, you can create a QItemEditorFactory that associates your editor with the correct type. This also works well with custom types.
When indicated by your view's EditTrigger, your view will get the delegate specific to the cell on which the edit is being invoked and call delegate->createEditor(...) which can then size the combo box according to the options parameter as well as set the current entry to the value specified by the model, although most of this should be handled by the QStyledItemDelegate. Thus, you won't have to worry about the Qt::EditRole directly as the view will handle that.
Did you try and have a look at the following example from Qt :
Spin Box Delegate Example
Maybe it will give you a much clearer view on the subject !
Hope it helps a bit !
