contentBrowserpanel ImguiRender

图片、文件获取

    for (auto& directoryEntry : std::filesystem::directory_iterator(m_CurrentDirectory))
        {
            const auto& path = directoryEntry.path();

            auto relativePath = std::filesystem::relative(path, s_AssetPath);

            Ref<Texture2D> icon = directoryEntry.is_directory() ? m_DirectoryIcon : m_FileIcon;
            ImGui::ImageButton((ImTextureID)icon->GetRendererID(), { thumbnailSize, thumbnailSize }, { 0, 1 }, { 1, 0 });
            if (ImGui::IsItemHovered() && ImGui::IsMouseDoubleClicked(ImGuiMouseButton_Left))
            {

                if (directoryEntry.is_directory())
                    m_CurrentDirectory /= path.filename();
            }
            ImGui::TextWrapped(filenameString.c_str());
            ImGui::NextColumn();


        }
        ImGui::Columns(1);
        ImGui::SliderFloat("Thumbnail Size", &thumbnailSize, 16, 512);
        ImGui::SliderFloat("Padding", &padding, 0, 32);
        // TODO: status bar

        ImGui::End();

InguiLayer字体调整

        float fontSize = 18.0f;// *2.0f;
        io.Fonts->AddFontFromFileTTF("assets/fonts/opensans/OpenSans-Bold.ttf", fontSize);
        io.FontDefault = io.Fonts->AddFontFromFileTTF("assets/fonts/opensans/OpenSans-Regular.ttf", fontSize);
