SWT CTabFolder doesn't display when running from eclipse

SWT CTabFolder doesn't display when running from eclipse - eclipse

I am creating an app using WindowBuilder in eclipse 4.4.2. I've added CTabFolders and corresponding CTabItems. The tabs are displayed properly when Click the preview button(Quickly test/preview the window without compiling or running it) in windowbuilder.
Screen Shot===> http://i.imgur.com/Sx9TQrL.jpg
But the real problem is when I run the app,the tabs are not displayed.

Can anyone suggest a solution. Thanks in advance.

And Finally I've figured the problem in the code. The composite in the base layout was assigned with the StackLayout as follows.
Composite content = new Composite(shell, SWT.BORDER);
content.setLayout(new StackLayout());
content.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
When I changed the StackLayout to GridLayout, I got a working solution.
Composite content = new Composite(shell, SWT.BORDER);
content.setLayout(new GridLayout(1, false));
content.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));

JFace add a Text box near a RadioGroupFieldEditor

I try to add some preferences in the Eclipse menu and for that I create in JFace a RadioGroupFieldEditor section and near the last radio of the RadioGroupField, I want to have a text area, like in the picture below:
However I am not able to do this. I create a GridLayout with two columns, in one column I want the RadioGroupFieldEditor , in the other I want the text field. The text field is put below the RadioGroupField, not in the second column like I expect.
here is the code:
protected Control createContents(Composite parent) {
Composite fieldEditorParent = new Composite(parent, SWT.NULL);
GridLayout layout = new GridLayout();
layout.numColumns = 1;
layout.marginHeight = 0;
layout.marginWidth = 0;
fieldEditorParent.setLayout(layout);
fieldEditorParent.setFont(parent.getFont());
createAGroup(fieldEditorParent);
return fieldEditorParent;
}
private void createAGroup(Composite parent) {
Group group = new Group(parent, SWT.NONE);
group.setText("Group");
GridLayout layout = new GridLayout();
layout.numColumns = 1;
group.setLayout(layout);
GridData data = new GridData(GridData.FILL_HORIZONTAL);
data.grabExcessHorizontalSpace = true;
group.setLayoutData(data);
GridLayout subLayout = new GridLayout();
subLayout.numColumns = 3;
Composite expertUserComposite1 = new Composite(group, SWT.NONE);
expertUserComposite1.setLayout(subLayout);
new Button(expertUserComposite1, SWT.RADIO | SWT.LEFT);
new Label(expertUserComposite1, SWT.BEGINNING).setText("aaa");
new Text(expertUserComposite1, SWT.BORDER);
Composite expertUserComposite2 = new Composite(group, SWT.NONE);
expertUserComposite2.setLayout(subLayout);
new Button(expertUserComposite2, SWT.RADIO | SWT.LEFT);
new Label(expertUserComposite2, SWT.BEGINNING).setText("bbb");
Composite expertUserComposite3 = new Composite(group, SWT.NONE);
expertUserComposite3.setLayout(subLayout);
new RadioGroupFieldEditor(IExportCSVPreferences.DELIMITER_NAME_CURRENT,
"RadioGroup", 1,
new String[][] { { "line1", "line1" }, { "line2", "line2" }, { "line3", "line3" } },
expertUserComposite3);
new Text(expertUserComposite3, SWT.BORDER);
Composite expertUserComposite4 = new Composite(group, SWT.NONE);
expertUserComposite4.setLayout(subLayout);
new RadioGroupFieldEditor(IExportCSVPreferences.DELIMITER_NAME_CURRENT, "RadioGroup", 1,
new String[][] { { "line1", "line1" }, { "line2", "line2" }, { "line3", "line3" } }, expertUserComposite4,
true);
new Text(expertUserComposite4, SWT.BORDER);
}
Here is the result:

Plugin development: composite of button in a view plugin

I am using zest to create plugin that show graph. I am trying to create button that refresh the plugin. The button is working, and I see the graph in the view also. But, the button is taking a lot of space in the view, and limit the place for the graph.I want that the button want limit the graph place.. How can I fix it? Thanks]
public void createPartControl(Composite parent) {
//create refresh button
Composite container = new Composite(parent, SWT.NONE);
container.setLayout(new GridLayout(1, false));
Button btnMybutton = new Button(container, SWT.PUSH);
btnMybutton.setBounds(0, 10, 75, 25);
btnMybutton.setText("Refresh Graph");
btnMybutton.addSelectionListener(new SelectionListener() {
#Override
public void widgetSelected(SelectionEvent e) {
init();
}
#Override
public void widgetDefaultSelected(SelectionEvent e) {
// TODO Auto-generated method stub
}
});
// Graph will hold all other objects
graph = new Graph(parent, SWT.NONE);
}

If you want to show the button on top of the graph, you should use a FormLayout instead of a GridLayout:
public void createPartControl(Composite parent) {
//create refresh button
Composite container = new Composite(parent, SWT.NONE);
container.setLayout(new FormLayout()); // Use FormLayout instead of GridLayout
Button btnMybutton = new Button(container, SWT.PUSH);
// btnMybutton.setBounds(0, 10, 75, 25); This line is unnecessary
// Assign the right FormData to the button
FormData formData = new FormData();
formData.left = new FormAttachment(0, 5);
formData.top = new FormAttachment(0, 5);
btnMybutton.setLayoutData(formData);
btnMybutton.setText("Refresh Graph");
// Use SelectionAdapter instead of SelectionListener
// (it's not necessary but saves a few lines of code)
btnMybutton.addSelectionListener(new SelectionAdapter() {
#Override
public void widgetSelected(SelectionEvent e) {
init();
}
});
// Graph will hold all other objects
graph = new Graph(container, SWT.NONE); // Note parent changed to container
// Assignt the right FormData to the graph
FormData formData2 = new FormData();
formData2.left = new FormAttachment(0, 0);
formData2.top = new FormAttachment(0, 0);
formData2.right = new FormAttachment(100, 0);
formData2.bottom = new FormAttachment(100, 0);
graph.setLayoutData(formData2);
}

Trying to set the size/location of a button in a tab for SWT

This should be pretty simple but this is the first time I've worked with SWT. This is what I have so far.
public class TabsTest {
private Shell shell;
private CTabFolder folder;
public TabsTest(Display display){
shell = new Shell(display);
shell.setText("TabsTest");
shell.setLayout(new FillLayout());
CTabFolder folder = new CTabFolder(shell, SWT.CLOSE | SWT.BOTTOM);
folder.setUnselectedCloseVisible(false);
folder.setSimple(false);
initUI(folder);
shell.pack();
shell.setBounds(500, 500, 400, 500);
shell.open ();
while(!shell.isDisposed()){
if(!display.readAndDispatch())
display.sleep();
}
}
public void initUI(CTabFolder folder){
CTabItem NFL = new CTabItem(folder, SWT.NONE);
NFL.setText("NFL Bets");
Button okButton = new Button(folder, SWT.PUSH);
okButton.setText("OK");
okButton.setSize(10,10);
NFL.setControl(okButton);
CTabItem NBA = new CTabItem(folder,SWT.NONE);
NBA.setText("NBA Bets");
CTabItem CFB = new CTabItem(folder,SWT.NONE);
CFB.setText("CFB Bets");
folder.setSize(800,500);
}
public static void main (String [] args) {
Display display = new Display();
new TabsTest(display);
display.dispose();
}
}
What this currently gives me is this....
How would I make this a small button in the bottom right corner? Or just in general make it smaller and move it somewhere.

Since you are using a FillLayout the control takes up the entire space available. What you need is a different kind of a layout. I will suggest you to read this article, it will be a good start.
I generally prefer GridLayout as it is quite easy to use and it fulfills most needs.
Edited: Modifying your code to use GridLayout

SWT - Getting Selected Rows from Table

I am trying to write a method that will get the current selections from the table and create a ArrayList from the selections.
Method:
public void getPlotterSelection() {
selPrinters = new ArrayList<PrinterProfile>();
int[] row = table.getSelectionIndices();
Arrays.sort(row);
if (row.length > 0) {
for(int i = row.length-1; i >= 0; i--){
PrinterProfile pp = new PrinterProfile(aa.get(i).getPrinterName(), aa.get(i).getProfileName());
selPrinters.add(pp);
}
}
}
This is the error I am getting
ERROR: 16:16:49,503 - TcLogger$IC_LogListener.logging:?

The problem is with this line of code
int[] row = table.getSelectionIndices();
Once again..
I am trying to get the user selected rows in the table and put them in a arraylist.

This is the button that calls the method

okButton.setEnabled(true);
okButton.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent e) {

});

I would suggest you to user Table viewer rather than Table. It makes your life easier. I see that you are showing table in a dialog. I guess your dialog is getting closed/disposed when you click OK before it get to getPlotterSelection() method.

So now I have successfully added a TableViewer in my TitleAreaDialog.
I am trying to figure out some of layout issues I am having.
Can I control the layout and location of my tableViewer in my Dialog window.
Right now the table is showing up on the right side.
I want it to be centered in my parent Composite.
Can I add the TableViewer to a Parent Layout in the createDialogArea method?
I will be adding more composites to the Dialog and would like to be able to control where they go and how they look.
Also my table shows a half empty column at the end of the table, is there a way to remove that?
Something like:
GridData gridData = new GridData();
gridData.grabExcessHorizontalSpace = true;
gridData.horizontalAlignment = GridData.CENTER;
TableViewer d = createTableViewer(area);
d.setLayoutData(gridData);
This is my createDialogArea code.
protected Control createDialogArea(Composite parent) {
final Composite area = new Composite(parent, SWT.NULL);
final GridLayout gridLayout = new GridLayout();
gridLayout.marginWidth = 15;
gridLayout.marginHeight = 10;
area.setLayout(gridLayout);
TableViewer d = createTableViewer(area);
return area;
}
Here is my tableviewer code
private TableViewer createTableViewer(Composite parent) {
viewer = new TableViewer(parent, SWT.MULTI | SWT.H_SCROLL | SWT.V_SCROLL | SWT.FULL_SELECTION | SWT.BORDER);
createColumns(parent, viewer);
final Table table = viewer.getTable();
table.setHeaderVisible(true);
table.setLinesVisible(true);
viewer.setContentProvider(new ArrayContentProvider());
viewer.setInput(AplotSelectedDataTable.getInstance().getArrayData());
// Layout the viewer
GridData gridData = new GridData(SWT.CENTER);
gridData.verticalAlignment = GridData.FILL;
gridData.horizontalSpan = 2;
gridData.grabExcessHorizontalSpace = true;
gridData.grabExcessVerticalSpace = true;
gridData.horizontalAlignment = GridData.FILL;
viewer.getControl().setLayoutData(gridData);
return viewer;
}

Here is a small example that should help you with your layout issues:
public class TestClass extends Dialog {
private TableViewer viewer;
protected TestClass(Shell parentShell) {
super(parentShell);
}
protected Control createDialogArea(Composite parent) {
final Composite area = new Composite(parent, SWT.NONE);
final GridLayout gridLayout = new GridLayout(2, true);
gridLayout.marginWidth = 15;
gridLayout.marginHeight = 10;
area.setLayout(gridLayout);
area.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
createButtons(area);
createTableViewer(area);
return area;
}
private void createButtons(Composite parent)
{
Button button1 = new Button(parent, SWT.PUSH);
button1.setText("Button1");
button1.setLayoutData(new GridData(SWT.CENTER, SWT.FILL, true, true));
Button button2 = new Button(parent, SWT.PUSH);
button2.setText("Button2");
button2.setLayoutData(new GridData(SWT.CENTER, SWT.FILL, true, true));
}
private void createTableViewer(Composite parent) {
viewer = new TableViewer(parent, SWT.MULTI | SWT.H_SCROLL
| SWT.V_SCROLL | SWT.FULL_SELECTION | SWT.BORDER);
createColumns(parent);
final Table table = viewer.getTable();
table.setHeaderVisible(true);
table.setLinesVisible(true);
viewer.setContentProvider(new ArrayContentProvider());
// Layout the viewer
GridData gridData = new GridData(SWT.CENTER, SWT.FILL, true, true);
gridData.horizontalSpan = 2;
table.setLayoutData(gridData);
}
private void createColumns(Composite parent)
{
TableViewerColumn viewerColumn = new TableViewerColumn(viewer, SWT.NONE);
final TableColumn column = viewerColumn.getColumn();
column.setText("Title");
column.setWidth(100);
column.setResizable(true);
column.setMoveable(false);
}
public static void main(String[] args) {
Display display = Display.getDefault();
final Shell shell = new Shell(display);
TestClass test = new TestClass(shell);
test.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
}
It basically creates a small Dialog with 2 buttons at the top and a centered TableViewer below. This should give you an idea on how to solve your problem.
