# imgui.create

> Creates a tracked ImGui window record and returns an ImGuiWindow object. The title argument defaults to "REAL_IM_UI" when omitted or nil. The title must be unique among currently tracked ImGui windows; creating another tracked window with the same title raises a Lua error.

<div className="real-function-page">
  ```lua theme={null}
  imgui.create(title?: string): ImGuiWindow
  ```

  ## Arguments

  <ParamField path={"title"} type={"string"}>
    Optional window title. When omitted or nil, "REAL\_IM\_UI" is used. A duplicate title among currently tracked ImGui windows raises a Lua error.
  </ParamField>

  ## Returns

  <ResponseField name={"window"} type={"ImGuiWindow"}>
    ImGuiWindow object with the window methods registered on its methods.
  </ResponseField>

  ## Types

  ### ImGuiWindow

  Handle returned by imgui.create. Control-building methods return the same handle so calls can be chained.

  ## Example

  Create one tracked ImGui window and append controls to the returned ImGuiWindow userdata.

  ```lua theme={null}
  local window = imgui.create("Runtime settings")

  window:Text("Controls")
  window:Separator()

  window:Checkbox("Enabled", true, function(enabled)
      print("Enabled:", enabled)
  end)

  window:SliderFloat("Opacity", 0.8, 0, 1, function(value)
      print("Opacity:", value)
  end)

  window:InputText("Label", "Real", function(text)
      print("Label:", text)
  end)

  window:ColorPicker("Accent", 0.3, 0.6, 1, 1, function(red, green, blue, alpha)
      print(red, green, blue, alpha)
  end)

  window:CollapsingHeader("Advanced", function(section)
      section:Text("Advanced controls go here")
  end)
  ```
