[Paraview-developers] checked and unchecked properties

[Biddiscombe, John A.]

Whilst I've got your attention....



Suppose I want to create a widget with a field array list, and a button, and another small control, and I have a custom property

vtkSMDataArrayProperty (a subclass of vtkStringVectorProperty), if I create a small pqPanel to encapsulate the behaviour I want, can i get it created automatically when the pqNamedObjects stuff is run.



What I'm after is (simplified)

vtkCustomBooleanProperty

to create a small gui control of my creation instead of a checkbox, so that inside the pqNamedWidgets, my control is generated



I manually changed the code to allow one special one already
    else if(pt == pqSMAdaptor::ENUMERATION)
      {
      if (SMProperty->IsA("vtkSMCommandProperty"))
        {
        QPushButton* button;
        button = new QPushButton(propertyLabel, panelLayout->parentWidget());
        button->setCheckable(1);
        button->setObjectName(propertyName);
        panelLayout->addWidget(button, rowCount, 0, 1, 2);
        button->show();
        rowCount++;
        }

so I can have a button instead of a checkbox for a vtkSMCommandProperty (such as "restart simulation"), but now I need a more complex control with a field array selection, and a button and some other stuff. I'm sure I can stuff my own widget in there if I want, but I'm worried about the connection of the events and property updates. Are there any other complex sub-controls anywhere that I can crib off ? I'm happy to hack quite deeply.

It's like someone just lifted a blanket off my head. I see so much more clearly now.



Cheers. As always, you're a great help.

unchecked property values are not pushed or saved in state or

anything. They are only used by domains to update themselves. The GUI

sets them when the user changes a GUI widget before hitting apply,

without changing the actual property value.



e.g. ArrayListDomain needs the field-selection property to show either

cell or point arrays. Now in the GUI when the user changes the field

selection to "cell" he expected to see the cell arrays listed even

before he has hit apply. For that, the ArrayListDomain needs to use

the user-selected value, not the actual property value. In such cases,

the GUI sets the unchecked value for the property and updates the

domain.
