Cannot type in Dear ImGui textbox

[AnClark]

Hi @falkTX !

I found that I'm unable to type any text in Dear ImGui textbox (ImGui::InputText() or other text input widgets). Only VST2 format can type.

Same problem occurs in Dear Plugins as well.

Do you have any idea?

Note:

• Metrics Tool shows that Dear ImGui does not receive any char queue.
• Dear ImGui can handle Enter and Backspace keys normally.

Which OS and plugin host are you using?

Which OS and plugin host are you using?

• I'm using Arch Linux with KDE.
• I'm testing Dear Plugins.

* I'm using Arch Linux with KDE.

Plugin host, not window manager :)
Aka: which program is hosting the VST2 plugin?

Do you get the same result with other plugin formats?

Do you get the same result with other plugin formats?

Sure. Both VST3 and **Standalone (JACK) ** has the same result (cannot type text).

You can try the current Dear Plugins repo to reproduce this issue.

which program is hosting the VST2 plugin?

REAPER.

I am unable to reproduce the issue on my system (Debian Stable with Fluxbox WM).
Both Jack standalone and VST3 (in REAPER) work correctly.

I didn't need to do this, but you may need to enable "Send all keyboard input to plugin":

OK. now Text Editor plugin works well on VST2 and VST3. But Standalone still have issue.

Update: But it's not stable enough on REAPER. Sometimes even VST2 still cannot type anything.

How to reproduce this issue:

1. Build ImGuiDemo (or Text Editor) in Dear Plugins.
2. Add plugin's VST3 binary to REAPER's scan path.
3. Run reaper -new to start REAPER, add an ImGuiDemo VST3 instance to a new track.
4. In plugin GUI, expand "Input & Focus", type something. At this time, "Chars queue" should show what character you typed.
5. Close FX Window, then retry Step 4. You will see that you cannot type anything anymore.
