text hovered

My Issue/Question:

Is it possible to hope for the developing of text hover style?

You can create your own widget easily for that.

Here's a potential solution that handles formatting:

header

namespace ImGui
{
    void TextWithHoverColor(ImVec4 col, const char* fmt, ...);
};

implementation

#include "imgui_internal.h"

void ImGui::TextWithHoverColor(ImVec4 col, const char* fmt, ...)
{
    ImGuiContext& g = *GImGui;
    ImGuiWindow* window = GetCurrentWindow();
    if (window->SkipItems)
        return;

    // Format text
    va_list args;
    va_start(args, fmt);
    const char* text_begin = g.TempBuffer;
    const char* text_end = g.TempBuffer + ImFormatStringV(g.TempBuffer, IM_ARRAYSIZE(g.TempBuffer), fmt, args);
    va_end(args);

    // Layout
    const ImVec2 text_pos(window->DC.CursorPos.x, window->DC.CursorPos.y + window->DC.CurrLineTextBaseOffset);
    const ImVec2 text_size = CalcTextSize(text_begin, text_end);
    ImRect bb(text_pos.x, text_pos.y, text_pos.x + text_size.x, text_pos.y + text_size.y);
    ItemSize(text_size, 0.0f);
    if (!ItemAdd(bb, 0))
        return;

    // Render
    bool hovered = IsItemHovered();
    if (hovered)
        PushStyleColor(ImGuiCol_Text, col);
    RenderText(bb.Min, text_begin, text_end, false);
    if (hovered)
        PopStyleColor();
}
