Daiane, thanks for your response. I make sure the calibration is ok because I re-calibrate it using xinput_calibretor tool. When I do the touch test I run the "xinput test XX" on the background, the print coordinate match the point that of I touch. When I open the sub-windows of QT app, there have "cancel" button on the right-bottom , "X" icon on the right-up region. I can close the sub-windows by click the "cancel" button, but fail by click the "X" icon of the sub-windows. The sub-window region only cover at the center of the screen. So, do you test the yacto touchscreen by multi-touch message ?
