Examples with ITitle org.swtchart.ITitle used on opensource projects

Example 1 with ITitle

use of org.swtchart.ITitle in project linuxtools by eclipse.

the class PieChartPaintListener method adjustTitle.

// Adjust the title with trailing blanks so it centers in the plot area
// rather than for the entire chart view which looks odd when not
// centered above the pie-charts themselves.
private void adjustTitle(PaintEvent pe) {
    ITitle title = chart.getTitle();
    Font font = title.getFont();
    Font oldFont = pe.gc.getFont();
    pe.gc.setFont(font);
    Control legend = (Control) chart.getLegend();
    Rectangle legendBounds = legend.getBounds();
    int adjustment = legendBounds.width - 15;
    // $NON-NLS-1$
    Point blankSize = pe.gc.textExtent(" ");
    int numBlanks = ((adjustment / blankSize.x) >> 1) << 1;
    String text = origTitleText;
    for (int i = 0; i < numBlanks; ++i) // $NON-NLS-1$
    text += " ";
    pe.gc.setFont(oldFont);
    title.setText(text);
