Hello,
I have to show some name value pairs in a dialog.
The dialog has a fixed size (PPC).
I used GridLayout with two columns.
The scheme is as folowing:
date label (1. column) | concrete date (2. column)
descr label | description text
An example:
....
date: 09.25.04
description: Now a longer description which
contains many words.
date: 09.28.04
description: Now a longer description which
contains many words.
....
The problem is the label with the description, which needs
often more than one row. I need a multi line label but SWT
declared SWT.MULTI not for labels.
Thats why, I tried a text field with text.setEnabled(false);
for showing the description. But that causes two problems:
1. I have to set the height of the description text field so
that the height is sufficient but not bigger.
GridData.FILL_VERTICAL lets free space and gridData.heighHint
demands the optimal height of the label which I don't know.
I tried also with pack() but had no success.
2. The font looks disabled and because I set
setEnabled(false) setForeGround(black) and so on has no
effect.
That seems to be a simple problem but I searched a solution
for a long time without result. Does anybody know how I
can display multi line labels?
Regards, Tobi

Hi Richard,
thank you for your answer. I also tried:
text.setEditable(false);
text.setBackground(white);
instead:
text.setEnabled(false);
Then the background and foreground color is ok but
the text has a cursor and can marked.
While the problem 2 is 'only' ugly, the first one is more important
because the app is for Pocket PC and there space is thinly distributed.
Regards, Tobi

Here is a possible solution that is using the StyledText widget
from the SWT custom package:
public class Main {
public static void main(String[] args) {
Display display = new Display();
Shell shell = new Shell(display);
shell.setLayout(new FillLayout());
final StyledText st = new StyledText(shell, SWT.MULTI | SWT.READ_ONLY);
st.setText("Hello World");
st.setCursor(display.getSystemCursor(SWT.CURSOR_ARROW));
st.setCaret(null);
st.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent e) {
st.setSelection(0);
}
});
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) {
display.sleep();
}
}
}
}
Just set the background to gray or something like that.

Why is the same algorithm not necessary using a Text control with SWT.WRAP.
