implot context menu inside node editor

[Analysiszaj]

Version/Branch:

latest

Back-ends:

glfw + openGL

Compiler, OS:

macOS + clang17

Details:

I downloaded the latest one imgui-bundle, I tried using the demo 'sandbox_plot_in_node.cpp' below, I found that when I right-click to open the pop-up box of the chart, it shows strange cropping, and sometimes a part is missing。

Minimal, Complete and Verifiable Example code:

Based on sandbox_plot_in_node.cpp

void gui()
{
    static ImVec2 plotSize(200, 200);
    static ImVec2 plotSize2(200, 200);
    static double xPos = 5.f;

    auto myPlotFunction = []()
    {
        static std::vector<float> x(1000), y(1000);
        for (int i = 0; i < 1000; ++i)
        {
            x[i] = i * 0.01f;
            y[i] = sin(x[i]);
        }
        ImPlot::PlotLine("My Line", x.data(), y.data(), 1000);
        ImPlot::DragLineX(0, &xPos, ImVec4(1, 1, 0, 1));
    };

    auto myPlotFunction2 = []()
    {
        static std::vector<float> x(1000), y(1000);
        for (int i = 0; i < 1000; ++i)
        {
            x[i] = i * 0.01f;
            y[i] = sin(x[i]);
        }
        ImPlot::PlotLine("My Line", x.data(), y.data(), 1000);
        ImPlot::DragLineX(0, &xPos, ImVec4(1, 1, 0, 1));
    };

    ed::Begin("My Node Editor");
    ed::BeginNode(ed::NodeId(1));
    ImGui::Text("Hello");
    ImGui::Text("World");
    plotSize = ImmApp::ShowResizablePlotInNodeEditor("My Plot", plotSize, myPlotFunction);
    ed::EndNode();

    ed::BeginNode(ed::NodeId(2));
    ImGui::Text("Hello");
    ImGui::Text("World");
    plotSize2 = ImmApp::ShowResizablePlotInNodeEditor("My Plot2", plotSize2, myPlotFunction2);
    ed::EndNode();

    ed::End();
}

Finally, Thank you for this amazing library!

Hello,

This issue is due to imgui-node-editor: popups may cause issue inside the node editor (and the context menu is rendered inside a popup).

See related imgui-node-editor issue: https://github.com/thedmd/imgui-node-editor/issues/242

ImGui Bundle addresses most of the issues by applying patches described in this issue, however this particular render issue is not easy to solve.
