How to select a qComboBox programmatically in Simple Filters module

Support
1

Hi,everyone. I’m trying to using code to substitute a series of mouse clicking and I get into trouble, please guide me.
In the first step, I need to select the first item in ‘OutputVolume’.(‘OutputVolume’ is a qComboBox).
In the second step, I need to select another, it means the second item in ‘OutputVolume’.

The apperance of this problem is when I click every qComboBox and select, every thing goes right, however, when I set the qComboBox programmly, it seems like I haven’t changed the ‘OutputVolume’ though the words showed is changed. And the result by program is same as when I only do the first step by clicking, but skip the second step.

I guess the problem is, in the second step, these 2 lines below,

OutputVolume=SimpleFiltersWidgetWhole[7]
OutputVolume.setCurrentNodeIndex(1)

which seems to only change what is showed visually in the qComboBox, but don’t truely get the item selected. In other word, it seems I need one more ‘click’ on the item to get it selected.

I loaded 2 .nii as volume.Hi,everyone. I’m trying to using code to substitute a series of mouse clicking and I get into trouble, please guide me.

Rather than trying to script the GUI, you could just use the SimpleITK code directly:
