Uitzonderingen

Voorbeelden

In het volgende codevoorbeeld wordt de ChunkSpaceThickness eigenschap gebruikt om de grootte van elke rechthoek te bepalen die een verhoging van de voortgangsbalk vertegenwoordigt die door de DrawVerticalChunks methode wordt getekend. Dit codevoorbeeld maakt deel uit van een groter voorbeeld voor de ProgressBarRenderer klasse.

    // Initialize the rectangles used to paint the states of the
    // progress bar.

            (NumberChunks * (ProgressBarRenderer::ChunkThickness + 
            (2 * ProgressBarRenderer::ChunkSpaceThickness))) + 6);

        // progress bar.

Deze waarde wordt bepaald door de huidige visuele stijl van het besturingssysteem.

Voordat u deze eigenschap opent, moet u controleren of de IsSupported eigenschap wordt geretourneerd true.
