How to create editorWidget when delegate is constructed?

[hjohn]

no editor widgets are set up when the delegate is constructed. We only construct an editor widget when it is needed.

here ,it says so.

So what if I want an editorWidget as soon as a delegate is created?

@hjohn Just construct it after creating the delegate?

@jsulm
What I mean is, in this QSpinBox Delegate example,when we click on particular block in the table , the QSpinBox gets created and as soon as we select some other index, it vanishes.
Is there a way to create a QSpinBox along with the Delegate where as soon as the table appears the spinBox appears too, without us clicking or attempting to edit it ? It should work as it works in the example linked above.

Hi,

Do you mean that you want the spin box to be shown permanently ?

[hjohn]

@SGaist Yes, thats exactly what I mean.
Can it be done !?

You can try with openPersistentEditor. Note that you will hit a performance penalty if your model has a big number of rows.

@SGaist Thank you
Now if there are more than one editors to add, How it knows which editor is to open in
void openPersistantEditor(const QModelIndex &index)?

That is implemented in the delegate createEditor function.
