Label cut off when changing text using SWT
So I build a shell that looks like the following
After I click the change path button, I prompt for the path and then set the text. The problem is after doing so new text gets cut off if its too long like so.
I am using a Label to display the path, and the only method I'm using in the listener regarding the Laebl is the setText() method. Is there a way to not have this happen? I am using SWT and prefer to maintain the grid layout so I can have the 2 columns. Any info would be helpful. Thank you.
Here's the code
String unit[] = {"Pixil", "Inch"};
final CustomAttribute realWidth = new CustomAttribute(String.valueOf(obj.getGraph().getWidth(null)));
final CustomAttribute realHeight = new CustomAttribute(String.valueOf(obj.getGraph().getHeight(null)));
double[] sizes = obj.convertToSizes();
if(sizes != null){
realWidth.setValue(sizes[0]);
realHeight.setValue(sizes[1]);
}
final Shell shell = new Shell(d);
shell.setImage(ApplicationPlugin.getImage(ApplicationPlugin.QUATTRO_ICON));
shell.setLayout(new org.eclipse.swt.layout.GridLayout(2,true));
shell.setText(EDIT_IMG_WINDOW_TITLE);
//width info
final Label labelWidth = new Label(shell, SWT.HORIZONTAL);
final Text textWidth = new Text(shell,SWT.SINGLE | SWT.BORDER);
//height info
final Label labelHeight = new Label(shell, SWT.HORIZONTAL);
final Text textHeight = new Text(shell,SWT.SINGLE | SWT.BORDER);
//units info
final Combo unitCombo = new Combo (shell, SWT.READ_ONLY);
final Button ratioBox = new Button (shell, SWT.CHECK);
ratioBox.setText(EDIT_IMG_RADIO);
//path info
final Button pathButton = new Button (shell, SWT.PUSH);
pathButton.setText(EDIT_IMG_PATH);
final Label pathText = new Label(shell, SWT.HORIZONTAL);
pathText.setText(obj.getTextData()[0]);
Button change = new Button (shell, SWT.PUSH);
change.setText(EDIT_IMG_SAVE_BUTTON);
ModifyListener heightListener = new ModifyListener(){
public void modifyText(ModifyEvent e) {
if(realImgListen && textHeight.getText() != ""){
realImgListen = false;
try{
double oldHeight = realHeight.getDouble();
double newHeight = Double.parseDouble(textHeight.getText());

The width of your columns is currently being set to the width of the widest control - probably 'Maintain Image Ratio'. If you set the the path text to anything longer than that it will be truncated.
You could set a width hint on the path control to set its size:
GridData data = new GridData(SWT.FILL, SWT.CENTER, true, false);
data.widthHint = 100; // You choose the width
pathText.setLayoutData(data);
Note that you have specified that the columns are of equal width so this will add similar space to the first column. You might want to switch to unequal width columns.
Alternatively you can ask the Shell to recalculate the size after you set the new text. Just call:
shell.pack();

It looks like that you are redrawing the change path label components and you are not wrapping the label . That why at the time of redrawing some part of the text is not visible.
Use warping or you can also increase the screen size
