M.Sz.

you're right. I see an issue in imgui repo: https://github.com/ocornut/imgui/issues/3572 maybe the suggested workaround, would work?

from https://github.com/ocornut/imgui imgui_demog.cpp: ```cpp if (ImGui::BeginTable("table_scrolly", 3, flags, outer_size)) { ImGui::TableSetupScrollFreeze(0, 1); // Make top row always visible ImGui::TableSetupColumn("One", ImGuiTableColumnFlags_None); ImGui::TableSetupColumn("Two", ImGuiTableColumnFlags_None); ImGui::TableSetupColumn("Three", ImGuiTableColumnFlags_None); ImGui::TableHeadersRow(); // Demonstrate using clipper for...

> ImGuiListClipper work on the vertical axis which is were the count can grow the most. Both TableSetColumnIndex() and TableNextColumn() return a bool reporting the column visibility so you can...

as an alternative, we can update the internal `imgui` tables mechanism like suggested in https://github.com/ocornut/imgui/issues/3572#issuecomment-885744366 so, to sum up: there are 2 possible workarounds 1. externally affect imgui table to...

okey, I got it: `imgui.GetItemRectSize()`

hmm, well, but is there anything like `CalcItemRectSize`? I need to get this value before rendering a widget

okey. so there is workaround code: ```golang startPos := GetCursorPos() var widgetWidth float32 // render widget with 0 alpha and store thems widths imgui.PushStyleVarFloat(imgui.StyleVarID(StyleVarAlpha), 0) mywidget.Build() size := imgui.GetItemRectSize() widgetWidth...

@krisives it was fixed in #9. I just put the `fix #x` in a wrong place :grinning:

@dertseha sadly, I'm not much familiar with C/cgo so idk if I'll be able to solve this problem. But, sure, if I get some time, I can play with that.

Hi, Now it works. Thanx, BUT should works, I suppose: `ffmpeg version 4.2.4 Copyright (c) 2000-2020 the FFmpeg developers` `gcc (GCC) 10.2.1 20201125 (Red Hat 10.2.1-9)`
