I want to open a View which includes table when operation is executed.
I can open view by viewId by that code:
display.asyncExec(new Runnable(){
public void run() {
ApplicationGIS.getView(true, viewId);
}});
This view's id defined on plugin.xml but I have to pass some parameters to the table on this view. I can create my custom view programatically but this time i can't open it becuase I don't have its id. Here is my view class:
public class MyCustomView extends ViewPart {
private Text text;
private Table table;
private TableViewer tableViewer;
#Override
public void createPartControl(Composite parent) {
// TODO Auto-generated method stub
parent.setLayout(new GridLayout(4, false));
Composite composite = new Composite(parent, SWT.NONE);
composite.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true, 4, 1));
composite.setLayout(new GridLayout(2, false));
text = new Text(composite, SWT.BORDER);
text.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false, 1, 1));
Composite composite_1 = new Composite(composite, SWT.NONE);
composite_1.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true, 2, 1));
GridLayout gl_composite_1 = new GridLayout(1, false);
gl_composite_1.horizontalSpacing = 0;
gl_composite_1.marginHeight = 0;
gl_composite_1.marginWidth = 0;
gl_composite_1.verticalSpacing = 0;
composite_1.setLayout(gl_composite_1);
tableViewer = new TableViewer(composite_1, SWT.BORDER | SWT.FULL_SELECTION);
table = tableViewer.getTable();
table.setHeaderVisible(true);
table.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true, 1, 1));
}
#Override
public void setFocus() {
// TODO Auto-generated method stub
}
}
So how can I access this programmatically created view and open it?
In Eclipse 3.x you can open a View like this:
MyView view = (MyView) PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().showView(viewer_ID);
Or if you are implementing a command handler, you can call:
HandlerUtil.getActiveWorkbenchWindow(event).getActivePage().showView(viewId);
To set some content you can simply add a method like void setInput(MyContent input) to your ViewPart and pass the needed arguments to this method, after opening it.
I had the exact same problem. I wanted to create additional views from the one registered in the plugin. These URL's will get you what you want:
http://wiki.eclipse.org/FAQ_How_do_I_open_multiple_instances_of_the_same_view
http://www.java-tips.org/other-api-tips/eclipse/how-to-create-multiple-instances-of-one-viewpart.html
PlatformUI.getWorkbench().getActiveWorkbenchWindow().
getActivePage().showView(String viewID,String secondaryID,int Mode);
From #Chriss answer;
I added a method setInput(parameter) to my view and then I can pass my values to my custom view like this
MyCustomView view = new MyCustomView();
view.setInput(parameter);
display.asyncExec(new Runnable(){
public void run() {
ApplicationGIS.getView(true, viewId);
}});
and this works.

I have two tables, on flag i need to show one table at a time. My createControl() method is called at the time of loading and flag value is true so one table is loaded first time, when choose of false flag my second table its giving null pointer. because second time table is not called correctly. i seen in google that stacklayout will work for this type of loading which will load two table at the time of load. but i am not able to call them using stacklayout.
public void createControl(final Composite parent) {
final Font font = parent.getFont();

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));
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));
Composite findComposite = new Composite(RightComposite, SWT.NONE);
findComposite.setLayout(new GridLayout(2, true));
findComposite.setLayoutData(new GridData(SWT.FILL, GridData.FILL, true, false));
txt = new Text(findComposite, SWT.BORDER | SWT.WRAP | SWT.SINGLE);
txt.setLayoutData(new GridData(SWT.FILL, GridData.FILL, true, false));
txt.addListener(SWT.Verify, new Listener()
{
#Override
public void handleEvent(final Event e)
{
newString = ((Text) e.widget).getText();
}
});
btn = new Button(findTCComposite, SWT.NONE);
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 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

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

I have an eclipse plug-in with a single view (like the eclipse helloworld-view-plugin-project). In the view-file I get an event when I want to update the view.
In this view I have a GridData in a Group with multiple labels. I have several services which register to the programe and whose status should be shown in this GridData.
Edit: In order to better show my problem I updated this post and added the whole code:
CreatePartControl():
public void createPartControl(Composite _parent) {
parent = _parent;
createContents();
addBindings();
makeActions();
contributeToActionBars();
}
CreateContents():
protected void createContents() {
// fixed
checkIcon = //...
errorIcon = //...
smallFont = SWTResourceManager.getFont("Segoe UI", 7, SWT.NORMAL);
// content
gl_shell = new GridLayout(1, false);
//margins, etc. for gl_shell
parent.setLayout(gl_shell);
final Label lblGreeting = new Label(parent, SWT.NONE);
lblGreeting.setLayoutData(new GridData(SWT.FILL, SWT.TOP, false, false, 1, 1));
lblGreeting.setText("Hi " + Preferences.getPreName());
// -- GROUP YOUR STATS (show all services)
createStatusGroupBox();
}
createStatusGroupBox():
private Group grpYourStatus = null; // outside the method for access in listener (below)
private void createStatusGroupBox() {
grpYourStatus = new Group(parent, SWT.NONE);
grpYourStatus.setLayoutData(new GridData(SWT.FILL, SWT.TOP, true, false, 1, 1));
grpYourStatus.setText("Your upload status");
grpYourStatus.setLayout(new GridLayout(3, false));
// add message if no service is registered
if ( r.getServiceList().size() == 0 ) {
Label status = new Label(grpYourStatus, SWT.NONE);
status.setText("No service registered.");
new Label(grpYourStatus, SWT.NONE); //empty
new Label(grpYourStatus, SWT.NONE); //empty
}
// add labels (status, message, name) for each registered service
for ( IRecorderObject service : r.getServiceList() ) {
Label name = new Label(grpYourStatus, SWT.NONE);
Label status = new Label(grpYourStatus, SWT.NONE);
Label message = new Label(grpYourStatus, SWT.NONE);
message.setFont(smallFont);
message.setLayoutData(new GridData(SWT.LEFT, SWT.CENTER, true, false, 1, 1));
service.getServiceViewItem().setLabelsAndIcons(name, status, message, checkIcon, errorIcon); //this also sets the values of the labels (label.setText(...) via data binding)
}
Unfortunately, I don't know what the right way is to update/reset it. I tried the following:
listener (which should update the view / the services-list):
r.addPropertyChangeListener(BindingNames.SERVICE_ADDED, new PropertyChangeListener() {
public void propertyChange(final PropertyChangeEvent evt) {
Display.getDefault().asyncExec(new Runnable() {
public void run() {
// This "redraws" the view, but just places the whole content (generated in createStatusGroupBox()) above the other parts.
//Display.getCurrent().update();
//createStatusGroupBox();
//parent.layout(true);
//parent.redraw();
// disposes grpYourStatus-Group but doesn't show anything then
grpYourStatus.dispose();
createStatusGroupBox();
grpYourStatus.layout();
grpYourStatus.redraw();
}
});
}
});
I also tried the following statements (individually); all without success:
parent.redraw();
parent.update();
parent.layout();
parent.layout(true);
parent.refresh();
In this post I read the following:
createPartControls is that time of the life cycle of a view, where its
contained widgets are created (when the view becomes visible
initially). This code is only executed once during the view life
cycle, therefore you cannot add anything here directly to refresh your
view.
Eclipse parts typically update their content as a reaction to a
changed selection inside of the workbench (e.g. the user might click
on another stack frame in the debug view).
Unfortunately, I don't know what to else I could try and I didn't find anything helpful with searches... thank's for your help and suggestions!
I finally found the answer (together with AndreiC's help!):
my listener now looks like this:
r.addPropertyChangeListener(BindingNames.SERVICE_ADDED, new PropertyChangeListener() {
public void propertyChange(final PropertyChangeEvent evt) {
Display.getDefault().asyncExec(new Runnable() {
public void run() {
// remove grpYourStatus from parent
grpYourStatus.dispose();
// add grpYourStatus (with updated values) to parent
createStatusGroupBox();
// refresh view
parent.pack();
parent.layout(true);
}
});
}
});
The rest is the same like the code above.
I do not know the API by heart, but have you tried parent.update()?
