I am facing a problem in creating calender dialog in rap application.
i have wriiten the code n getting compliation error
private void onPaint(PaintEvent event) {
Rectangle rect = getClientArea();
GC gc0 = event.gc;
Image image = new Image(m_Display, rect.width, rect.height); GC gc = new GC(image);


gc.setBackground(m_Display.getSystemColor(SWT.COLOR_WIDGET_B ACKGROUND));
gc.fillRectangle(rect);
int x = 0;
int y = 0;
for (int i = 0; i < 7; i++) {
if (i == 0)
gc.setForeground(m_Display.getSystemColor(SWT.COLOR_RED));
else
gc.setForeground(m_Display.getSystemColor(SWT.COLOR_BLACK));


String text = getDayName(i);
Point size = gc.stringExtent(text);
gc.drawText(text, x + (m_ColSize-size.x)/2, (m_RowSize-size.y)/2, true);
x += m_ColSize;


}
gc.setForeground(m_Display.getSystemColor(SWT.COLOR_BLACK));
y += m_RowSize;
gc.drawLine(0, 0, rect.width, 0);
gc.drawLine(0, y - 1, rect.width, y - 1);
//


m_Calendar.set(Calendar.YEAR, m_Year);
m_Calendar.set(Calendar.MONTH, m_Month);
int day = 1;
while (true) {
m_Calendar.set(Calendar.DAY_OF_MONTH, day);
if (m_Calendar.get(Calendar.MONTH) != m_Month)

break;
int day_of_week = calendarDayToNormal(m_Calendar.get(Calendar.DAY_OF_WEEK));
Point p = getDayPoint(day);
if (day == m_Day) {

//gc.setForeground(m_Display.getSystemColor(SWT.COLOR_LIST_S ELECTION_TEXT));
gc.setForeground(m_Display.getSystemColor(SWT.COLOR_BLUE));


gc.setBackground(m_Display.getSystemColor(SWT.COLOR_LIST_SEL ECTION));
}
else {
gc.setBackground(m_Display.getSystemColor(SWT.COLOR_WIDGET_B ACKGROUND));
if (day_of_week == 0)
gc.setForeground(m_Display.getSystemColor(SWT.COLOR_RED));

else
gc.setForeground(m_Display.getSystemColor(SWT.COLOR_BLACK));
}
String text = ""+day;
Point size = gc.stringExtent(text);
gc.drawText(text, p.x + ((m_ColSize-size.x)/2), p.y + ((m_RowSize-size.y)/2), true);


day++;
}
gc0.drawImage(image, 0, 0);
gc.dispose();
image.dispose();

Hi,
currently, GC drawing is only supported on Canvas, but not on image -
see bug:
318900: Image class doesn't implement Drawable
https://bugs.eclipse.org/bugs/show_bug.cgi?id=318900
If you want to create a Calandar, you can use DateTime widget with
SWT.CALENDAR style flag or SWT.DATE | SWT.DROP_DOWN.
HTH,
Ivan

Hi mamta,
seems like you call new Display() several times. Use <some
control>.getDisplay() instead.
HTH,
Ivan
