 static void DrawButton(System::Drawing::Graphics ^ g, System::Drawing::Rectangle bounds, System::Windows::Forms::VisualStyles::PushButtonState state);

public static void DrawButton(System.Drawing.Graphics g, System.Drawing.Rectangle bounds, System.Windows.Forms.VisualStyles.PushButtonState state);

static member DrawButton : System.Drawing.Graphics * System.Drawing.Rectangle * System.Windows.Forms.VisualStyles.PushButtonState -> unit

Public Shared Sub DrawButton (g As Graphics, bounds As Rectangle, state As PushButtonState)

Parameters

Opmerkingen

Als visuele stijlen zijn ingeschakeld in het besturingssysteem en visuele stijlen worden toegepast op de huidige toepassing, tekent deze methode de knop met de huidige visuele stijl. Anders wordt de knop getekend met de klassieke Windows stijl.

Voorbeelden

In het volgende codevoorbeeld wordt de methode in de DrawButton(Graphics, Rectangle, String, Font, Boolean, PushButtonState) methode van OnPaint een aangepast besturingselement gebruikt om een knop te tekenen in de status die wordt bepaald door de locatie van de muis aanwijzer. Dit codevoorbeeld maakt deel uit van een groter voorbeeld voor de ButtonRenderer klasse.

    // Draw the large or small button, depending on the current state.
protected:
    virtual void OnPaint(PaintEventArgs^ e) override
    {
        __super::OnPaint(e);

        // Draw the smaller pressed button image
        if (state == PushButtonState::Pressed)
        {
            // Set the background color to the parent if visual styles
            // are disabled, because DrawParentBackground will only paint
            // over the control background if visual styles are enabled.

Opmerkingen

Als visuele stijlen zijn ingeschakeld in het besturingssysteem en visuele stijlen worden toegepast op de huidige toepassing, tekent deze methode de knop met de huidige visuele stijl. Anders wordt de knop getekend met de klassieke Windows stijl.
