Modeless & Modal

  • Hello guys,
    I am trying to open the 2nd ui by clicking the Push button on the 1st UI with modal & Modeless. It is working fine but my requirement is to pop up the 2nd ui by plotting the XY Graph using QCustomPlot libraries. So I have invoked the xygraph function in the 2nd UI class to get plot with the given values but I am getting run termination.
    So please Help me how to pop up the 2nd window with the plotted graph when I clicked the push button on the first UI using QCustomPlot libraries.
    Thanks in advance
