Draws a set of progress bar pieces that fill a vertical progress bar.
public:
static void DrawVerticalChunks(System::Drawing::Graphics ^ g, System::Drawing::Rectangle bounds);
public static void DrawVerticalChunks(System.Drawing.Graphics g, System.Drawing.Rectangle bounds);
static member DrawVerticalChunks : System.Drawing.Graphics * System.Drawing.Rectangle -> unit
Public Shared Sub DrawVerticalChunks (g As Graphics, bounds As Rectangle)
The operating system does not support visual styles.
-or-
Visual styles are disabled by the user in the operating system.
-or-
Visual styles are not applied to the client area of application windows.
The following code example uses the DrawVerticalChunks method in a Timer.Tick event handler to draw each increment of a progress bar. This code example is part of a larger example provided for the ProgressBarRenderer class.
// Handle the timer tick; draw each progressively larger rectangle.
private:
void progressTimer_Tick(Object^ myObject, EventArgs^ e)
{
if (ticks < NumberChunks)
{
Graphics^ g = this->CreateGraphics();
ProgressBarRenderer::DrawVerticalChunks(g,
progressBarRectangles[ticks]);
ticks++;
}
else
{
progressTimer->Enabled = false;
}
}
// Handle the timer tick; draw each progressively larger rectangle.
private void progressTimer_Tick(Object myObject, EventArgs e)
{
if (ticks < NumberChunks)
{
using (Graphics g = this.CreateGraphics())
{
ProgressBarRenderer.DrawVerticalChunks(g,
progressBarRectangles[ticks]);
ticks++;
}
}
else
{
progressTimer.Enabled = false;
}
}
' Handle the timer tick; draw each progressively larger rectangle.
Private Sub progressTimer_Tick(ByVal myObject As [Object], ByVal e As EventArgs)
If ticks < NumberChunks Then
Dim g As Graphics = Me.CreateGraphics()
Try
ProgressBarRenderer.DrawVerticalChunks(g, progressBarRectangles(ticks))
ticks += 1
Finally
g.Dispose()
End Try
Else
progressTimer.Enabled = False
End If
End Sub
Each progress bar piece drawn by this method spans the width of the bounds
parameter. The number of progress bar pieces drawn is determined by the height of bounds
and the values returned by ChunkSpaceThickness and ChunkThickness.
Before using this method, you should verify that the IsSupported property returns true
.
