imgui_positioning

Plug and play extension for imgui allowing window docking or screen relative positions.

The configuration window will highlight the selected, as well as hovered windows in docking/anchoring mode, to easily visualise which window is target.

A line is drawn from the anchor to the window.

These extended settings will be stored at imgui.ini.ext. The current imgui.ini path is read from the IO context.

Usage

You will have to call ImGuiExt::UpdatePosition() before ImGui::Begin(). Its return value determines whether the window should have a NoMove flag or not.

Before ImGui::End() you should call ImGuiExt::ContextMenuPosition(). You need specify a name for your context menu. This way you can append to an existing context menu.

void Render()
{
	ImGuiWindowFlags wndFlags
		= ImGuiWindowFlags_AlwaysAutoResize
		| ImGuiWindowFlags_NoCollapse
		| ImGuiExt::UpdatePosition("MyWindow###EvenWithID"); // adds 0 or the NoMove flag. Depending on configuration.

	if (ImGui::Begin("MyWindow###EvenWithID", 0, wndFlags))
	{
		/* window contents */
	}

	if (ImGui::BeginPopupContextWindow("MyWindow###EvenWithID##ContextMenu", ImGuiPopupFlags_MouseButtonRight))
	{
		/* other context menu options */
		ImGui::EndPopup();
	}
	ImGuiExt::ContextMenuPosition("MyWindow###EvenWithID##ContextMenu"); // ID matches other context menu

	ImGui::End();
}
