My Issue/Question:
Hi!
I'm wondering how I could move & constraint the size the TabBar of a docking panel onto my custom title bar.
Here is my current setup:
Currently, everything under the custom title bar is just empty space that my docking window is taking.
I have tried using the DockNodeBeginAmendTabBar/DockNodeEndAmendTabBar but it seems to only be useful to modify the content of the tab bar(like adding elements before or after).
Here is what I tried:
// Creating the dockspace
ImGuiWindowClass top_level_class;
top_level_class.ClassId = ImHashStr("SceneEditor");
top_level_class.DockingAllowUnclassed = false;
ImGui::DockSpace(ImGui::GetID("SceneEditorDockSpace"), {0, 0}, 0, &top_level_class);
// Offsetting the tab bar vertically to step onto the title bar above it
ImGuiDockNode* node = (ImGuiDockNode*)GImGui->DockContext.Nodes.GetVoidPtr(ImGui::GetID("SceneEditorDockSpace"));
ImGui::SetCursorPosY(ImGui::GetCursorPosY() - 32); // <--- This has no effect
if(ImGui::DockNodeBeginAmendTabBar(node))
{
ImGui::SetNextItemWidth(48);
if (ImGui::BeginTabItem("##logoPadding", 0, ImGuiTabItemFlags_Leading))
{
ImGui::EndTabItem();
}
ImGui::DockNodeEndAmendTabBar();
}Another solution I thought of is to hide the actual tab bar, and make one from scratch that mimicks the actual real tab bar.
Is there any system that would allow me to avoid making one from scratch and simply move/size the real tab bar?
Thanks!
