You
can define Progress bar widget using ProgressBar class.
Following
statements define horizontal progress bar.
ProgressBar
horizontalProgressBar = new ProgressBar(shell, SWT.HORIZONTAL);
horizontalProgressBar.setMaximum(100);
horizontalProgressBar.setMinimum(10);
horizontalProgressBar.setBounds(50,
50, horizontalScaleWidth, horizontalScaleHeight);
horizontalProgressBar.setBackground(new
Color(display, 255, 255, 255));
horizontalProgressBar.setSelection(30);
Following
statements define vertical progress bar.
ProgressBar
verticalProgressBar = new ProgressBar(shell, SWT.VERTICAL);
verticalProgressBar.setMaximum(1000);
verticalProgressBar.setMinimum(500);
verticalProgressBar.setBounds(250,
150, verticalScaleWidth, verticalScaleHeight);
verticalProgressBar.setBackground(new
Color(display, 255, 255, 255));
verticalProgressBar.setSelection(650);
Following
is the complete working application.
