Feel free to discuss anything regarding ImGuiCS (the ImGui.NET fork) itself here.

I need "ImGuiColorTextEdit" component, I think I already have my answer but do you have a tool to help C++ to C# conversion ?

0x0ade commented 6 years ago

Unfortunately no. I've attempted something similar by converting imguifilesystem with the replace function step by step and then fixing it by hand, but never finished fixing it completely.

I wish C# had an easy way to interop with C++ libraries, as it'd make using existing ImGui components so much easier.

fxgenstudio commented 6 years ago

Could you update ImguiCS to last Imgui 1.54 ? Thanks.

0x0ade commented 6 years ago

I'll try to do it this week, but no promises as I'll also have an exam this week.

How to do C++ ImGui::GetWindowDrawList()->AddImage(...) in CS ?

0x0ade commented 6 years ago

I've just added the missing AddImage binding to ImDrawList and moved a method to match its native counterpart: https://github.com/0x0ade/ImGuiCS/commit/39e0fc50473fe8c2358b4b175005de5503db4f7b, https://github.com/0x0ade/ImGuiCS/commit/e8d3930d7155af0ab8c8692afb403d047ccedf61

ImGui::GetWindowDrawList()->AddImage(...)

becomes

ImGui.GetWindowDrawList().AddImage(...)

In XNA and FNA, you need to register your texture to the ImGuiXNAState. The Register method returns the ID you need to use.

Note that I haven't had time to test this yet. Please tell me if this does or doesn't work.

fxgenstudio commented 6 years ago

Thanks that work ! I display texture font.

@procfxgen I'll attempt to update the bindings to 1.54 after cimgui 1.54 drops, which should happen shortly after ImGUI 1.54 itself gets released.

Please note that I can only build cimgui 1.54 for Windows x64 and Linux x64. We'll need to wait until someone builds cimgui 1.54 binaries for macOS x64 and all x86 variants.

Is there any way I can hide the close button of a window?

0x0ade commented 6 years ago

@zeaga It should be possible by doing this:

bool opened = false;
ImGui.Begin("Window Title", ref opened /*, ...*/);

Please tell me if this works or not, I currently can't test it.

zeaga commented 6 years ago

Nope, didn't work unfortunately.

0x0ade commented 6 years ago

ImGUI 1.60 has finally been released: https://twitter.com/ocornut/status/982759513672634374

Unfortunately I'm busy with other projects right now, which means that I'm (hopefully) going to update ImGuiCS later this month.

fxgenstudio commented 6 years ago

Perfect !

0x0ade commented 6 years ago

The underlying C binding - cimgui - hasn't been updated to ImGui 1.60 just yet: https://github.com/Extrawurst/cimgui/issues/49

ImGuiCS and ImGui.NET rely on cimgui, as C# can't natively (without using helpers) interop with C++ in a cross-platform manner.

I'll update ImGuiCS after cimgui's master branch supports 1.60.
