potential libraries to include

[dcnieho]

Hi Pascal,

I saw https://github.com/CoolLibs/imgui_gradient, which might be of interest to include
And it could be worth considering to replace https://github.com/dfranx/ImFileDialog with https://github.com/time-killer-games/libfiledialogs

Cheers!

Hi Dee,

I'm gonna transform this issue into a discussion inside discussions/ideas, as it will better fit as a discussion.

Now, concerning those two:

• https://github.com/CoolLibs/imgui_gradient
  I'll keep this in the idea box. The API is quite extensive, and thus not immediate to bind. Will see later if more users ask for it.

• And it could be worth considering to replace https://github.com/dfranx/ImFileDialog with https://github.com/time-killer-games/libfiledialogs

A good idea. However, I recommend you take a look at the bindings for Portable File Dialogs. They are easy to use, and use the OS dialogs, which is what the final users want, IMHO.

[dcnieho]

Yeah, I agree that Portable File Dialogs is likely what many users want. But since you offer ImFileDialog already and that seems unmaintained and somewhat buggy, swapping it out for the other one could be useful.

One problem i have had is making a selection dialogue for multiple folders--that seems to not be a native thing so portable file dialogues doesn't do it. I'm not sure whether libfiledialogs does it, never tried, and have my own solution. But at least I'd be implementable there if i ever want to.

[dcnieho]

Here's another one you could consider replacing, the colorized text editor.
As per BalazsJako/ImGuiColorTextEdit#128, it has been unmaintained for years and this won't change.
dfranx has a form that has advanced a lot, but also seems dead for the last two years: https://github.com/dfranx/ImGuiColorTextEdit
This one however seems to be actively worked on: https://github.com/santaclose/ImGuiColorTextEdit

Since the current editor has some annoying bugs (like that you can't mouse-click to the end of a line), it is worth considering to replace with santaclose's fork.

ImGuiColorTextEdit is now based on the santaclose fork

[dcnieho]

Super! Do you plan to do a new release soon so i can try it out?

[dcnieho]

And i see you just did last week :p I shall try it out!

Hi Dee,

Concerning ImGuiColorTextEdit, I know that it is not maintained. I already added a list of interesting forks, and santaclose is part of them. However, what this fork changes is not well documented (apart from reading the commit log). As written in the forks.md file I suspect it mainly adds support for multicursor, auto-indentation and python.

I think I took inspiration from for the python language support which I added in my fork.

Concerning the mouse click at end of line, I fixed it about a month ago in pthom/ImGuiColorTextEdit@0708c7a

I also improved the default color palette in pthom/ImGuiColorTextEdit@bc44d0a

---

Concerning ImFileDialog's fork https://github.com/time-killer-games/libfiledialogs, its code is too bloated (it mixes the code from SDL, imgui, lunasvg, as well as some dll all into the same repository), I cannot use it as is. Its author contacted me, and I wrote him about this.

[dcnieho]

Ah ok! Didn't know you fixed that bug (just tried the demo and indeed) and indeed, the situation with not well-documented and diverging forks is not ideal.
Too bad that ImFileDialog fork isn't integratable, but i understand.

Is there a guide about how to "bind some c++ lib to python, then use it alongside imgui_bundle"? (or is it possible for imgui_bundle to leave some area for other program to draw on)

Like integrating https://github.com/glampert/debug-draw into imgui, something like this: https://www.youtube.com/watch?v=aE8p9937syw

[district10]

Surfing GitHub for a while (months..) and I found vedo is what i'm looking for. (there's also an imgui integration via polyscope, example here). Hope one day imgui-bundle can be integrated with vedo. 😄

See doc about litgen, the generator behind ImGui Bundle

or is it possible for imgui_bundle to leave some area for other program to draw on

@dcnieho : I just added support for MatPlotLib images:

If you are interested in vedo, you could take inspiration from this

I just took a look at recent imgui_bundle, the immvision is awesome! I use some similiar panzoom viewer (in browser) to inspect SVG, really helpful when a closer look is needed.

Then, how about nanovg. 😅

[pthom]

I added NanoVG support recently. It was quite a complex and long task, but it works.

see python bindings, code of python demos, code of C++ demos, online full demo, online simple demo, and API for integration with ImGui. Works on Linux, Windows, macOS, emscripten, iOS and Android (OpenGL only)

[pthom]

Please, if possible, post images of your results - with NanoVG or other - in the gallery

[dcnieho]

On windows, i have a hiDPI problem with the full demo. Well, parts of it, the widgets and text are way too small.

This was an issue with the official demo of NanoVG, which does not support HighDPI. I did a recent adaptation

@district10 many thanks for those nice suggestions. I’m on holiday so it might take me a while to study those, but I will have a look.
