Custom Window title bar height change affects dragging

[Gellert5225]

Version/Branch of Dear ImGui:

Version 1.89.2, Branch: Docking

Back-ends:

imgui_impl_OpenGL.cpp

Compiler, OS:

Windows 10 + MSVC 2022

Full config/build information:

No response

Details:

My Issue/Question:

I made a custom window using ImGui::Begin(...), and I changed its title bar height using

ImGui::PushStyleVar(ImGuiStyleVar_FramePadding, ImVec2(4.0f, 10.0f));
ImGui::Begin(...);
ImGui::PopStyleVar();

// UI inside the window

ImGui::End();

However, when I tried to drag the window around, the only drag-able area is very tiny, not spanning the entire height of the title bar.

As shown in the image, only area above that red line is drag-able. It's the same area as if I didn't change the frame padding.

What am I doing wrong here? Thanks.

Thanks for reporting. I can confirm there is an issue, which only happens when io.ConfigWindowsMoveFromTitleBarOnly is enabled.

I'm adding the 'docking' label to this issue because it pertain to another issue we have to make it easier to create widget that move windows with/without undocking. Right now the way the logic is performed (geometry testing every frame instead of maintaining a small bit of state) is causing both issues.

@ocornut Would you mind linking the issue/PR you mentioned above?

I don't think there's a GitHub issue for it.

I just wanted to add a comment here that I looked for making those bars a bit bigger and then found this report on web search, so would also appreciate if we can fix this :-)
