[libcamera-devel] [PATCH v2 10/11] qcam: ControlFrame: Add GUI way to interact with ControlTypeIntger32

[Utkarsh Tiwari]

Add an integer slider for ControlTypeIntger32 control types.
The default value on the slider is the default value for the control
and it may not be the current value for the control.
