Examples

The following code example demonstrates how to use the GetPartSize(IDeviceContext, ThemeSizeType) method in a custom control to get the sizes of a window title bar, Close button, borders, and sizing handle specified by the visual style. These sizes are used to calculate the sizes of the Rectangle objects used to draw the VisualStyleElement objects that represent these window parts. This code example is part of a larger example provided for the VisualStyleRenderer class overview.

    // Get the sizes and offsets for the window parts as specified
    // by the visual style.
private:
    void GetPartDetails()
    {
        // Do nothing further if visual styles are not enabled.
        if (!Application::RenderWithVisualStyles)
        {
            return;
        }

        Graphics^ g = this->CreateGraphics();

        // Get the size and offset of the close button.
        if (SetRenderer(windowElements["windowClose"]))
        {
            closeButtonSize =
                renderer->GetPartSize(g, ThemeSizeType::True);
            closeButtonOffset =
                renderer->GetPoint(PointProperty::Offset);
        }

        // Get the height of the window caption.
        if (SetRenderer(windowElements["windowCaption"]))
        {
            captionHeight = renderer->GetPartSize(g,
                ThemeSizeType::True).Height;
        }

        // Get the thickness of the left, bottom,
        // and right window frame.
        if (SetRenderer(windowElements["windowLeft"]))
