Regular Buttons that work like radio buttons

[JeffM2501]

bool RadioButton(const char* text, int* activeItem, int thisItem)
{
	if (activeItem != nullptr && *activeItem == thisItem)
		ImGui::PushStyleColor(ImGuiCol_Button, ImGui::GetStyle().Colors[ImGuiCol_ButtonActive]);

	bool value = ImGui::Button(text);

	if (activeItem != nullptr && *activeItem == thisItem)
		ImGui::PopStyleColor();

	if (value && activeItem != nullptr)
		*activeItem = thisItem;

	return value;
}

Usage

        if (ImGui::Begin("radio window", nullptr))
        {
            RadioButton("A", &currentButton, 0); ImGui::SameLine();
            RadioButton("B", &currentButton, 1); ImGui::SameLine();
            RadioButton("C", &currentButton, 2); ImGui::SameLine();
            RadioButton("D", &currentButton, 3);
        }
        ImGui::End();

Stumbled across this looking for this in C#. Here's the converted code (using Hexa Imgui). Thanks for the idea! It also assumes that activeItem is always set to a valid option value.

bool RadioButton(string text, ref int activeItem, int thisItem)
{
	if (activeItem == thisItem)
		ImGui.PushStyleColor(ImGuiCol.Button, ImGui.GetStyle().Colors[(int)ImGuiCol.ButtonActive]);

	bool value = ImGui.Button(text);

	if (activeItem == thisItem)
		ImGui.PopStyleColor();

	if (value)
		activeItem = thisItem;

	return value;
}
