Standalone, minimal, complete and verifiable example: (see #2261)
ImGui::Begin("Asset Browser");
if (ImGui::Button("Drag this"))
{
}
int dndData = 1;
if (ImGui::BeginDragDropSource(ImGuiDragDropFlags_None))
{
ImGui::SetDragDropPayload("DND_TEST", &dndData, sizeof(int));
ImGui::EndDragDropSource();
}
ImGui::End();
ImGui::Begin("Viewport");
ImGui::Text("Dropped count: %d", droppedCount);
if (ImGui::Button("Drop Here"))
{
}
if (ImGui::BeginDragDropTarget())
{
if (const ImGuiPayload* payload = ImGui::AcceptDragDropPayload("DND_TEST"))
{
droppedCount += *(const int*)payload->Data;
}
ImGui::EndDragDropTarget();
}
ImGui::End();
