How to create a toolbar inside viewpart (Not use plugin.xml) - swt

I Created a ToolItem "Save As" like image above, But it not display at toolbar position. So how to create a toolbar inside viewpart (Not use plugin.xml)
IMAGE EXAMPLE
This is my code Create Toolbar:
public void createToolbar(Composite parent) {
// Create composite Toolbar and set layout
toolBarComposite = new Composite(parent, SWT.NONE);
gridLayout = new GridLayout(1, false);
toolBarComposite.setLayout(gridLayout);
gridData = new GridData(SWT.RIGHT, SWT.NONE, true, false);
toolBarComposite.setLayoutData(gridData);
// Create Toolbar
gridData = new GridData(SWT.RIGHT, SWT.NONE, true, false);
toolBar = new ToolBar(toolBarComposite, SWT.FLAT);
toolBar.setLayoutData(gridData);
// Create Item
item = new ToolItem(toolBar, SWT.PUSH);
item.setImage(SAVE_IMAGE);
item.setToolTipText("Save (Ctrl + S)");
item.setEnabled(true);
item.addSelectionListener(new SelectionAdapter() {
private static final long serialVersionUID = -102212312093090431L;
#Override
public void widgetSelected(SelectionEvent e) {
}
#Override
public void widgetDefaultSelected(SelectionEvent e) {
}
});
}
Thank for your advance !

You're going to have to use contributions on the view site's action bar.
Example
// Copy-pasted from an existing project, so the code can be made nicer
private void createAdditionalToolbarActions()
{
getViewSite().getActionBars().getToolBarManager().add(new GroupMarker("additions")); //$NON-NLS-1$
getViewSite().getActionBars().getToolBarManager().prependToGroup("additions", new SaveAction()); //$NON-NLS-1$
getViewSite().getActionBars().updateActionBars();
}
The method getViewSite is part of ViewPart. Call this after the contents of the view have been created.
The SaveAction must implement IAction or IContributionItem. For convenience, just extend the SaveAction from org.eclipse.jface.action.Action and call methods such as setImageDescriptor and setToolTipText.
Do all your business login in the run override.

How to replace a button and re position it dynamically?

I have a text box and a add button next to it, when I click on add button I am able to add a text box and delete button next to it. Now I want the add button on the first row to be changed to delete and the add button should be re-positioned below two rows, when the second row delete button is clicked (the second row is deleted )the add button should go back to the first row and replace delete button. It should look like following.
How do I achieve this?
If you create a Composite as a container of sorts, you can add and remove from it allowing everything outside to remain in the correct order. By reserving the space, the delete button is always below the contents of the container.
I have a text box and a add button next to it, when I click on add button I am able to add a text box and delete button next to it
For example, if we have a small Shell with an add Button as you mentioned, and an empty space to add the Text widgets to:
final Composite baseComposite = new Composite(shell, SWT.BORDER);
baseComposite.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
baseComposite.setLayout(new GridLayout());
final Composite rowsContainerComposite = new Composite(baseComposite, SWT.BORDER);
rowsContainerComposite.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
rowsContainerComposite.setLayout(new GridLayout());
final Button addButton = new Button(baseComposite, SWT.PUSH);
addButton.setText("Add");
(For now the empty space is grabbing all available space, but you can change that as needed)
When adding rows, you can add to the rowsContainerComposite:
addButton.addSelectionListener(new SelectionAdapter() {
#Override
public void widgetSelected(final SelectionEvent e) {
new Row(rowsContainerComposite);
rowsContainerComposite.layout();
}
});
A sample Row class:
public class Row {
final Composite baseComposite;
public Row(final Composite parent) {
baseComposite = new Composite(parent, SWT.BORDER);
baseComposite.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, false));
baseComposite.setLayout(new GridLayout(2, false));
final Text text = new Text(baseComposite, SWT.BORDER);
text.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
final Button deleteButton = new Button(baseComposite, SWT.PUSH);
deleteButton.setText("Delete");
deleteButton.addSelectionListener(new SelectionAdapter() {
#Override
public void widgetSelected(final SelectionEvent e) {
baseComposite.dispose();
parent.layout();
}
});
}
}
when the second row delete button is clicked (the second row is deleted )the add button should go back to the first row
Then when deleted, rows will shift back appropriately:
the add button should be re-positioned below two rows
The idea is that by using the "container" composite, you're reserving that space to add and remove the rows from. The delete button will always be below the rows as they are added and removed.
Full example:
public class AddDeleteButtonTest {
private static class Row {
final Composite baseComposite;
public Row(final Composite parent) {
baseComposite = new Composite(parent, SWT.BORDER);
baseComposite.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, false));
baseComposite.setLayout(new GridLayout(2, false));
final Text text = new Text(baseComposite, SWT.BORDER);
text.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
final Button deleteButton = new Button(baseComposite, SWT.PUSH);
deleteButton.setText("Delete");
deleteButton.addSelectionListener(new SelectionAdapter() {
#Override
public void widgetSelected(final SelectionEvent e) {
baseComposite.dispose();
parent.layout();
}
});
}
}
private final Display display;
private final Shell shell;
public AddDeleteButtonTest() {
display = new Display();
shell = new Shell(display);
shell.setLayout(new FillLayout());
final Composite baseComposite = new Composite(shell, SWT.BORDER);
baseComposite.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
baseComposite.setLayout(new GridLayout());
final Composite rowsContainerComposite = new Composite(baseComposite, SWT.BORDER);
rowsContainerComposite.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
rowsContainerComposite.setLayout(new GridLayout());
final Button addButton = new Button(baseComposite, SWT.PUSH);
addButton.setText("Add");
addButton.addSelectionListener(new SelectionAdapter() {
#Override
public void widgetSelected(final SelectionEvent e) {
new Row(rowsContainerComposite);
rowsContainerComposite.layout();
}
});
}
public void run() {
shell.setSize(200, 200);
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) {
display.sleep();
}
}
display.dispose();
}
public static void main(final String... args) {
new AddDeleteButtonTest().run();
}
}
I did the same in one of my project. The code is bit complicated to do in Jface/SWT. Adding and removing widgets on composite will be bit heavy task. This will reduce UI performance.
If you use Jface tableviewer instead of creating composite, you will get better UI performance and good look as well. In table viewer in one column you can show textboxes and in one column you can show buttons. You can write table column Editing support/label providers to show the buttons.
With this approach you will be able show buttons for all rows or when you click on any cell you want to add or delete.
I can't share the code snippet right now, due to some reasons, but if you need I will share it on weekends

GXT ToolBar is scrolled

I'm developing a simple GXT widget - it's a TreePanel with a ToolBar added using setTopComponent.
The problem is that as soon as the tree is large enough so that it can be scrolled, the scroll-bar doesn't scroll the tree only, but scrolls the ToolBar as well.
What should be change so that ToolBar remains on the top of page, and only the tree is scrolled.
public class TreePanelExample extends LayoutContainer {
#Override
protected void onRender(Element parent, int index) {
super.onRender(parent, index);
Folder model = getTreeModel();
TreeStore<ModelData> store = new TreeStore<ModelData>();
store.add(model.getChildren(), true);
final TreePanel<ModelData> tree = new TreePanel<ModelData>(store);
tree.setDisplayProperty("name");
tree.setAutoLoad(true);
ToolBar toolBar = new ToolBar();
toolBar.setBorders(true);
toolBar.add(new Button("Dummy button", new SelectionListener<ButtonEvent>() {
public void componentSelected(ButtonEvent ce) {
Info.display("Dummy button", "I'm so dumb!");
}
}));
ContentPanel panel = new ContentPanel();
panel.setHeaderVisible(false);
panel.setCollapsible(false);
panel.setFrame(false);
panel.setAutoWidth(true);
panel.setAutoHeight(true);
// setting fixed size doesn't make any difference
// panel.setHeight(100);
panel.setTopComponent(toolBar);
panel.add(tree);
add(panel);
}
The problem is that
TreePanelExample extends LayoutContainer
while instead it should extend Viewport.
Additionally I shouldn't have used
panel.setAutoWidth(true);
panel.setAutoHeight(true);
Plus it is necessary to add the main panel using
new BorderLayoutData(LayoutRegion.CENTER);
Here is the complete solution:
public class TreePanelExample extends Viewport {
public TreePanelExample() {
super();
setLayout(new BorderLayout());
Folder model = getTreeModel();
TreeStore<ModelData> store = new TreeStore<ModelData>();
store.add(model.getChildren(), true);
final TreePanel<ModelData> treePanel = new TreePanel<ModelData>(store);
treePanel.setDisplayProperty("name");
treePanel.setAutoLoad(true);
ToolBar toolBar = new ToolBar();
toolBar.setBorders(true);
toolBar.add(new Button("Dummy button", new SelectionListener<ButtonEvent>() {
public void componentSelected(ButtonEvent ce) {
Info.display("Dummy button", "I'm so dumb!");
}
}));
ContentPanel panel = new ContentPanel();
panel.setBodyBorder(false);
panel.setHeaderVisible(false);
panel.setTopComponent(toolBar);
panel.setLayout(new FitLayout());
panel.add(treePanel);
BorderLayoutData centerData = new BorderLayoutData(LayoutRegion.CENTER);
centerData.setMargins(new Margins(5, 5, 5, 5));
centerData.setCollapsible(true);
panel.syncSize();
add(panel, centerData);
}

Double click event prob

When ever I double click the tree viewer file that file name should appear in the next form view
Sample.dat -> double click -> name should be appear Sample.dat and File related properties should be appear.
I created a treeViewer files and double click the file name that name is not appear.
Please kindly help me reg this,eclipse rcp,Juno,e4 etc..
Perspective class...
private void setLayouts(IPageLayout layout) {
// Range 0.05f to 0.95f....
IFolderLayout explorerFolderLayout = layout.createFolder("explorer", IPageLayout.LEFT, 0.25f, layout.getEditorArea());
explorerFolderLayout.addView(ExplorerView.ID);

You need to add click listener to your tree
final Tree tree = new Tree(parent, SWT.BORDER);
tree.addMouseListener(new MouseListener(){
public void mouseDoubleClick(MouseEvent e) {
//get data of selected element
//we use array[0], because we have not multiselect tree
MyDataObject data = (MyDataObject) tree.getSelection()[0].getData();
//now you need to pass "data" to your view with file info
//I don't know how to do it in pre e4 RCP apps, so
//please read this answer: https://stackoverflow.com/a/2227764/1030113
//hope that helps
}
public void mouseDown(MouseEvent e) {}
public void mouseUp(MouseEvent e) {}
});
//to test
TreeItem treeItem1 = new TreeItem(tree, SWT.NONE);
treeItem1.setText("some item 1");
treeItem1.setData(new MyDataObject("somedata 1"));
TreeItem treeItem2 = new TreeItem(tree, SWT.NONE);
treeItem2.setText("some item 2");
treeItem2.setData(new MyDataObject("somedata 2"));
I don't know how to communicate between view in pre e4 RCP apps, but I found some usefull answers here: https://stackoverflow.com/a/2227764/1030113

how to pop up calendar when button is clicked in Java SWT?

I am trying to develop Java SWT application in eclipse.
I need to populate text box using DateTime Calendar in SWT when a button is clicked.
I tried the following code but not able to see the Calendar, though it is created.
Any help would be appreciated.
Thanks
public void createPartControl(final Composite parent) {
Button button;
Label label;
final Display dev = parent.getDisplay();
Image image = new Image(dev,"C:\\Users\\rm186021\\Desktop\\Calendar.gif");
GridLayout gridLayout = new GridLayout();
gridLayout.numColumns = 3;
parent.setLayout(gridLayout);
label = new Label(parent, SWT.NULL);
label.setText("Start date ");
final Text start = new Text(parent, SWT.SINGLE | SWT.BORDER);
Button calButton = new Button(parent, SWT.PUSH);
calButton.setImage(image);
calButton.addSelectionListener(new SelectionAdapter() {
#Override
public void widgetSelected(SelectionEvent e) {
final Display display = new Display();
final Shell shell2 = new Shell(display);
shell2.addListener(SWT.CALENDAR, new Listener() {
public void handleEvent(Event event) {
final DateTime calendar = new DateTime(shell2,SWT.CALENDAR | SWT.POP_UP);
calendar.addSelectionListener (new SelectionAdapter () {
public void widgetSelected (SelectionEvent e) {
start.setData(" " + calendar.getYear() + "-" + (calendar.getMonth() + 1) + "-" + calendar.getDay());
System.out.println(start.getData());
//calendar.dispose();
}
});
}
});
}
});
You're creating a Shell, but never even opening it. Try calling shell2.open().
You're adding an SWT.CALENDAR listener to the Shell. This isn't going to do what you want to do. Or anything, for that matter, since Shell doesn't fire SWT.CALENDAR events. Instead, you simply need to add the DateTime to a container and hook up selection listeners to the Calendar.
SWT.POP_UP is not an appropriate style bit for Calendar.
I would recommend subclassing Dialog (call it CalendarDialog, for example), setting a FillLayout on it, adding a Calendar to it and hooking up listeners that way. Then call CalendarDialog.open().
The DateTime really shouldn't be created with code like that :) Try this instead:
calButton.addSelectionListener(new SelectionAdapter() {
#Override
public void widgetSelected(SelectionEvent e) {
final Shell shell2 = new Shell(dev.getActiveShell());
// new Display() won't work on many platforms if one already exists
final DateTime calendar = new DateTime(shell2, SWT.CALENDAR);
// no need to add a listener to shell2, and POP_UP doesn't work for DateTime
calendar.addSelectionListener(...);
shell2.open();
// Edward Thomson noticed it wasn't called, I missed it
}
};

SWT: show popup menu below toolbar button after clicking on it

I want to show a popup menu below a toolbar button when the user clicks this button. I've read about the SWT.DROP_DOWN style for a ToolItem but this seems very much limited to a simple list of items according to this sample. Instead, I want to show a popup menu with, e.g., checkbox and radio button menu items.
You can make MenuItem with styles SWT.CHECK, SWT.CASCADE, SWT.PUSH, SWT.RADIO, SWT.SEPARATOR
see javadoc..
So you can "hang" swt menu to selection of dropdown on toolbar item like this
public class Test {
private Shell shell;
public Test() {
Display display = new Display();
shell = new Shell(display, SWT.SHELL_TRIM);
shell.setLayout(new FillLayout(SWT.VERTICAL));
shell.setSize(50, 100);
ToolBar toolbar = new ToolBar(shell, SWT.FLAT);
ToolItem itemDrop = new ToolItem(toolbar, SWT.DROP_DOWN);
itemDrop.setText("drop menu");
itemDrop.addSelectionListener(new SelectionAdapter() {
Menu dropMenu = null;
#Override
public void widgetSelected(SelectionEvent e) {
if(dropMenu == null) {
dropMenu = new Menu(shell, SWT.POP_UP);
shell.setMenu(dropMenu);
MenuItem itemCheck = new MenuItem(dropMenu, SWT.CHECK);
itemCheck.setText("checkbox");
MenuItem itemRadio = new MenuItem(dropMenu, SWT.RADIO);
itemRadio.setText("radio1");
MenuItem itemRadio2 = new MenuItem(dropMenu, SWT.RADIO);
itemRadio2.setText("radio2");
}
if (e.detail == SWT.ARROW) {
// Position the menu below and vertically aligned with the the drop down tool button.
final ToolItem toolItem = (ToolItem) e.widget;
final ToolBar toolBar = toolItem.getParent();
Point point = toolBar.toDisplay(new Point(e.x, e.y));
dropMenu.setLocation(point.x, point.y);
dropMenu.setVisible(true);
}
}
});
shell.open();
while(!shell.isDisposed()) {
if(!display.readAndDispatch()) display.sleep();
}
display.dispose();
}
public static void main(String[] args) {
new Test();
}
}
