Resizing problem when using a glfw window with directx 11

[Ack008]

Hi everyone. I'm trying to create my own game engine using ImGui. I programmed in such a way that i can choose which API I can use to render the scene, I can choose between Directx 11 and Opengl, but in both cases i use a glfw window. With Opengl everything is fine, the problem comes with the second one.

The problem comes when i resize the window while I'm using the Directx11. When I resize it resize the swap chain, so i don't think that the problem is in the directx settings itself. In order to inizialize ImGui for D3DX11 I use the following code:

• ImGui_ImplGlfwInitForOther(win->GetWindow(),true);
• ImGui_ImplDX11Init(win->pDevice, win_->pContext); In the frame:
• ImGui_ImplDX11_NewFrame();
• ImGui_ImplGlfw_NewFrame(); and for the rendering:
• ImGui_ImplDX11_RenderDrawData(ImGui::GetDrawData()); (obviously I also use ImGui::New_Frame() and ImGui::Render();

Also the input coordinates are wrong after the resize, for example, also if I click outside the imgui window, imgui detect that I'm inside of it, otherwise, if I'm touching the window, ImGui doesn't detect it.

(Sorry for the bad english).

Check the value of io.DisplaySize and how it is updated by ImGui_ImplGlfw_NewFrame(). Perhaps some of the function there don't work with that specific setup? Also print the value of io.MousePos to see which side of the fence may be wrong.

I have the same problem in Win32 with DX11. I checked io.DisplaySize and io.MousePos and the values are updated correctly. Nonetheless, resizing the window stretches ImGui just as shown above.
