I would design TitleAreaDialog similar to those Eclipse but without sucess, below there is two screenshot, Eclipse form and my own form,
i have problem to get the top and bottom separator, if you notice,Eclipse form don't gave a margin and the workspace have margin.
in my own form my separator have a margin
Eclipse Form :

Could someone give me an idea how to get TiteAreaDialog similar to those of Eclipse ?
with my thank's
I finally solved the problem myself, after thoroughly looked at the code of the TitleAreaDilog class, I found that there was no way to do this directly.
with a little imagination I found the trick, it was necessary to create two nested Composites
the parent Composite without margin will contain the two separators and the child composite which have margin and will contain others controls.
as we you can see in the example below.
I hope this will help some beginners like me

In the createControl(parent) method of the Wizard Page, the code is as below-
top = new Composite(parent, SWT.NONE);
top.setLayout(new FillLayout());
setControl(top);
setPageComplete(false);
createViewer(top);
I want to add a row above the composite denoted by top.
It doesn't allows me. If I add it, the composite denoted by top gets lost.
The below is rendered for the top composite -
The moment I place the below code before the top composite, the top composite gets lost -
upper = new Composite(parent, SWT.NONE);
upper.setLayout(new FillLayout());
setControl(upper);
Label label = new Label(page, SWT.NONE);
label.setText("Some text to disply");
Please suggest on how to achieve the same.
The below is the createControl snippet in my case. It breaks the scrolling and size of the table viewer if add a row.

A wizard page must only have one top level composite. You can add multiple controls (including nested composites) to that composite.
So for a label above to table:
top = new Composite(parent, SWT.NONE);
top.setLayout(new GridLayout());
setControl(top);
Label label = new Label(top, SWT.NONE);
label.setText("Some text to disply");
label.setLayoutData(new GridData(SWT.BEGINNING, SWT.CENTER, false, false));
TableViewer viewer = new TableViewer(top, .... flags
viewer.getTable().setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
When trying to add a lot of labels on to a Composite that is contained in a ScrolledComposite after a certain number (1638) for me, it just seems to give up and stop drawing the components after it. Is this a hard limit on a number of things that can be displayed or something I'm doing wrong.
This also happens if I just add one label with 2000 lines of text in.
public class LoadsOfLabelsTestDialog extends Dialog
{
List<Label> displaylabels = new ArrayList<>();
Composite content, list;
ScrolledComposite scroll;
public LoadsOfLabelsTestDialog(Shell parentShell)
{
super(parentShell);
}
#Override
protected void configureShell(Shell shell)
{
super.configureShell(shell);
shell.setSize(new Point(700, 500));
shell.setText("FML"); //$NON-NLS-1$
}
#Override
public Control createDialogArea(final Composite comp)
{
content = (Composite) super.createDialogArea(comp);
content.setLayout(new GridLayout(1, false));
content.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
Button set1 = new Button(content, SWT.PUSH);
set1.setText("Display List 1");
set1.addSelectionListener(new SelectionAdapter() {
#Override
public void widgetSelected(SelectionEvent e) {
List<String> rows = new ArrayList<>();
for (int i = 0; i < 2000; i++) {
rows.add(i +" row");
}
updateList(rows);
}
});
scroll = new ScrolledComposite(content, SWT.V_SCROLL);
list = new Composite(scroll, SWT.NONE);
list.setLayout(new GridLayout(1, true));
scroll.setContent(list);
scroll.setExpandHorizontal(true);
scroll.setExpandVertical(true);
scroll.setLayoutData(new GridData(SWT.FILL, SWT.FILL, false, true));
new Label(content, SWT.HORIZONTAL | SWT.SEPARATOR);
setScrollSize();
return content;
}
private void setScrollSize() {
scroll.setMinSize(list.computeSize(SWT.DEFAULT, SWT.DEFAULT));
}
private void updateList(List<String> rows) {
if (this.displaylabels == null) {
this.displaylabels = new ArrayList<>();
}
for (Label l : displaylabels) {
l.dispose();
}
this.displaylabels.clear();
for (String item : rows) {
addListLabel(item);
}
content.layout(true, true);
setScrollSize();
}
private void addListLabel(String whoText) {
Label a = new Label(list, SWT.NONE);
a.setText(whoText);
this.displaylabels.add(a);
}
public static void main(String[] args)
{
Display d = new Display();
Shell s = new Shell();
LoadsOfLabelsTestDialog fml = new LoadsOfLabelsTestDialog(s);
fml.open();
}
}
You hit a hard limit, probably the maximum size of a control. While this limit may differ slightly on other platforms, you can't size a control arbitrarily.
As #greg-449 suggested, prefer using a Table. If the content per table row is more than just an image and text, you can add a paint listener to draw the row contents yourself.
I just started to learn Java. I have already looked Swing and at the moment I'm trying to do something with SWT.
But I have the next problem. Key Listener that I added for Text field is working, but inside this listener I can't change for example my label.
I have seen a few demos they worked, but I don't see any differences.
import org.eclipse.swt.SWT;
import org.eclipse.swt.events.KeyAdapter;
import org.eclipse.swt.events.KeyEvent;
import org.eclipse.swt.layout.*;
import org.eclipse.swt.widgets.*;
public class FirstClass {
public static void main(String[] args) {
Display display = new Display();
Shell shell = new Shell(display);
shell.setText("First Application");
GridLayout layout = new GridLayout(2, false);
shell.setLayout(layout);
Text word = new Text(shell,SWT.SINGLE | SWT.BORDER | SWT.FILL);
GridData wordGrDt = new GridData();
wordGrDt.heightHint = 130;
wordGrDt.minimumHeight = 130;
wordGrDt.horizontalAlignment = SWT.FILL;
wordGrDt.verticalAlignment = SWT.FILL;
wordGrDt.horizontalSpan = 2;
word.setLayoutData(wordGrDt);
GridData statusGrDt = new GridData();
statusGrDt.grabExcessHorizontalSpace = true;
statusGrDt.horizontalSpan = 1;
statusGrDt.horizontalAlignment = SWT.LEFT_TO_RIGHT;
Label status = new Label(shell, SWT.PUSH);
status.setEnabled(true);
status.setText("");
status.setLayoutData(statusGrDt);
GridData checkGrDt = new GridData();
checkGrDt.widthHint = 150;
checkGrDt.horizontalSpan = 1;
checkGrDt.horizontalAlignment = SWT.RIGHT_TO_LEFT;
Button check = new Button(shell, SWT.PUSH);
check.setText("Check");
check.setLayoutData(checkGrDt);
word.addKeyListener(new org.eclipse.swt.events.KeyAdapter() {
public void keyPressed(org.eclipse.swt.events.KeyEvent e) {
if (e.keyCode == SWT.CR) {
System.out.println("worked!!!");
status.setText("ababahalamaha");
}
}
});
shell.setMinimumSize(400, 300);
shell.open();
shell.pack();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) {
display.sleep();
}
}
display.dispose();
}
}
Add a layout() call to the parent of the Label:
word.addKeyListener(new org.eclipse.swt.events.KeyAdapter() {
public void keyPressed(org.eclipse.swt.events.KeyEvent e) {
if (e.keyCode == SWT.CR) {
System.out.println("worked!!!");
status.setText("ababahalamaha");
status.getParent().layout();
}
}
});
The label originally has a width of 0, as it doesn't contain any text. When you add content, the parent has to know to re-layout its children.
As a note:
Please check which style you use with which widget. A Label does not know what to do with the style SWT.PUSH for example.
Below is my code, When button press I am changing the item1 list by using item1.setcontrol depends on my condition.
Composite is not refreshing, But when I click on Item2 tab and come back to Item1 tab... List is updated depends on condition.
Please let me know How to refresh the layout with out moving to other Tab item.
final Composite RightComposite = new Composite(paComposite, SWT.NONE);
RightComposite.setLayout(new GridLayout(1, false));
RightComposite.setLayoutData(new GridData(SWT.FILL, GridData.FILL, true, true));

findComposite.setLayout(new GridLayout(2, true));
findComposite.setLayoutData(new GridData(SWT.FILL, GridData.FILL, true, false));

}
});

btn.setLayoutData(new GridData(SWT.BEGINNING, GridData.BEGINNING, false, false));
btn.setText("Find button");
final TabFolder tabFolder = new TabFolder(RightComposite, SWT.NONE);
tabFolder.setLayoutData(new GridData(SWT.FILL, GridData.FILL, true, true));
final TabItem item1 = new TabItem(tabFolder, SWT.NONE);
item1.setText("Tab 1 ");
btn.addListener (SWT.Selection, new Listener()
{
public void handleEvent(Event e) {
if(!newString.isEmpty()){
item1.setControl(list1);
}
else
{
item1.setControl(list);
}
}
});
TabItem item2 = new TabItem(tabFolder, SWT.NONE);
Item2.setText("Tab 2");
RightComposite.layout();
Your problem is in the SWT's TabItem class, in the setControl() function. At the end of this function it makes an: oldControl.setVisible (false);
So in your situation the oldControl will be the same control you set (it you set it twice) and it will be hidden. To solve the problem you can modify the code as:
btn.addListener (SWT.Selection, new Listener() {
public void handleEvent(Event e) {
if (!newString.isEmpty()) {
item1.setControl(list1);
list1.setVisible(true);
} else {
item1.setControl(list);
list.setVisible(true);
}
}
});
Or another approach:
btn.addListener (SWT.Selection, new Listener() {
public void handleEvent(Event e) {
if (newString != null && !newString.isEmpty()) {
if (item1.getControl() != list1) {
item1.setControl(list1);
}
} else {
if (item1.getControl() != list) {
item1.setControl(list);
}
}
}
});
I hope this fits your needs.
i created a Dialog with two input fields with the following Code.

}
#Override

return true;
}
// save content of the Text fields because they get disposed
// as soon as the Dialog closes
private void saveInput() {
CCID = ccidText.getText();
description = descriptionText.getText();
}
#Override
protected void okPressed() {
saveInput();
super.okPressed();
}
public String getCCID() {
return CCID;
}
public String getDescription() {
return description;
}
}
Is there a way to validate the ccidtext?
If the user type more then 7 chars, he must get a notification and should not be able to continue the dialog. I read so lot at the internet but can`t find a solution for this problem.
Thank u so much for your help.

You can use Text.addModifyListener to add a ModifyListener which will be called each time the text is changed. You can also use Text.addVerifyListener to add VerifyListener which can actually prevent text being entered.
For TitleAreaDialog you can call setMessage or setErrorMessage to display a message in the title area.
You can disable the OK button on the dialog using:
getButton(IDialogConstants.OK_ID).setEnabled(false);
Note: getButton(xxx) can return null if you call it too early in the dialog construction. Buttons are created during the createContents method after the createDialogArea method has been called.
So you can access the buttons by overriding createContents like this:
#Override
protected Control createContents(final Composite parent)
{
Control control = super.createContents(parent);
// TODO access buttons here
return control;
}
