Detailed Description

base class for objects that are using the frames generated by QCam objects.

The slot newFrame() wich must be implemented will be called when a new frame is avable on the associated QCam and when the QCamClient object is not paused.

Member Function Documentation

bool QCamClient::isActive

(

)

const [inline]

indicate if the client is active.

if true, the clien is connected to a cam, and is not paused.

QCam& QCamClient::cam

(

)

const [inline]

return the connected QCam object.

Must not be called if no QCam object is connected.

QWidget * QCamClient::buildGUI

(

QWidget *

parent

)

build the GUI related tgo the camera client.

buildGUI of base class should also be called

Reimplemented in QCamFindShift, and QCamFindShift_hotSpot.

virtual void QCamClient::newFrame

(

)

[protected, pure virtual, slot]

Slot to implement.

is is called for every new frame. Use cam().yuvFrame() to acces the to frame.

Implemented in CamHistogram, QCamDisplay, and QCamFindShift.
