Interaction between QT and ImGui/ImPlot

[sytuannguyen]

Dear Dev Team of ImPlot,

We are trying to use ImPlot for a geoscience application in which we need to mix the use of QT and ImGui/ImPlot under SDL. We found that ImGui/ImPlot is a great tools for our purpose.

The mix between QT and ImPlot is done by calling an ImPlot class from a menu in a QT window such as

// ImPlot class.
PlotSeismic::PlotSeismic(WorkingSetManager* manager):
ImGuiCore(),
m_manager(manager)
{}

// This function is called from a menu in QT window
void PetrophysicsTools::viewPlotSeismic()
{
// Here we call ImPlot class
PlotSeismic *w = new PlotSeismic(m_manager);
w->show();
}

However, actually we have an issue related to the fact that we could not open two SDL windows in parallel as well as interacting between a SDL window and a QT window. More precisely we cannot interact with a QT Window while ImGui is running.

Could you please confirm that it is possible to interact between a QT window and an ImPlot window such that we can display the position of the mouse moving on an ImPlot window to a QT window.

Help needed: if you know someone who are available to help us with this issue please contact us at stuan.nguyen@gmail.com

Sincerely,
Sy Tuan NGUYEN
