| Dear Matthew, Since, you do not have a right click, you can modify the zoomer such that "Shift+Right Click" will zoom the plot. So, basically add following line at Line 147 in TimeDomainDisplayPlot.cc d_zoomer->setMousePattern(QwtEventPattern::MouseSelect1, Qt::RightButton, Qt::ShiftModifier); You can similarly change other display plots according to your requirement. Let me know if this solves your problem. Regards, Kartik Patel |

I am developing an embedded device that uses the frequency and waterfall QT plot widgets. Problem is my platform has a touchscreen without a right mouse button implemented - so I can zoom in but not zoom back out. I would just like to disable the zoom behaviour entirely.Can someone familiar with the QT stuff please guide me where to change the mouse behaviour? I have tried commenting out some lines in various files in /gr-qtgui and recompiling with no success.Thanks!
