I am new to NatTable and was looking to print the NatTable.
I know about paperClips for SWT tables but couldn't find anything similar for Nattable.
has anyone tried printing or even saving the Nattable data as imagedata?
You can press CTRL+P while the NatTable has focus. This should give you a print dialog.
In code it will create a new PrintAction. Check out:
org.eclipse.nebula.widgets.nattable.print.action.PrintAction to see how that works.
That's true in case you are using a GridLayer with DefaultGridLayerConfiguration. There the DefaultPrintBindings are aggregated which add the binding for CTRL+P.
Also the PrintCommandHandler is registered against the GridLayer.
So if you are using a GridLayer, the above statement is perfectly correct, otherwise you need to ensure to register the PrintCommandHandler and the corresponding binding to your layer composition.

How can I change the positions of checkbox and label and how to implement a link into the label?
$acceptGTC = new Element\Checkbox('AGBs');
$acceptGTC->setLabel('I Accept the GTC (show it).');
$this->add($acceptGTC);

meanwhile:
I tried to overwrite the view helper for checkboxes.
copied
*/vendor/zendframework/zend-form/src/View/Helper/FormCheckbox.php
to
*/module/Application/src/Application/View/Helper/FormCheckbox.php
added to module.config.php
'viewhelpers' => array('checkbox'=>'Application\View\Helper'),
But it still uses the original one...
Do I have to tell zend to use my FormCheckbox?
I don't exactly know the way you are rendering your Zend_Form_Element, but in order to enhance the rendering as you want you should build a custom decorator, and add it to this element.
You should read the Zend documentation on Zend_Form_Decorators, everything is quite well explained and should lead you to a fancy solution.
I'm currently trying to develop an Eclipse Plugin to support code replacement, like what the default content assist in Eclipse do. What I want to implement is something like "insert argument names automatically on method completion with visualized box around the argument" and I can "use the Tab key to navigate between the inserted names" and "while navigating, list of optional variables for current argument can be displayed and be chosen".
In short, it comes to two questions:
How to add the visualized box around the already existed variable or even Java keywords that need replacement? And at the meanwhile I can use Tab key to switch between these boxes.
How to display a list of candidates to select from when I trigger on the box?
By now I only figure out the extension point : org.eclipse.jdt.ui.javaCompletionProposalComputer may be useful, but I have no idea where to start at? Thanks in advance.
Oh, finally I've solved it myself...
For the 'box', it should be the LinkedModeModel, this class should work with LinkedPositionGroup and LinkedPosition to add mutiple boxes. And we should use LinkedModeUI to set it up.
For the content assistant, there's no need to use the extension point. There is a ProposalPosition class which extends LinkedPosition for you to add your proposals for the 'box' in its constructor. And we can simply use the CompletionProposal to construct a ICompletionProposal array as the argument of ProposalPosition's constructor.
I am trying to set ids for tabs in the tabpanel. The code that I have written is:
Panel dateTab = new VerticalPanel();
queryTabPanel.addTab("Date", dateTab);
where queryTabPanel is another TabPanel.
My Problem: is to set Ids for the Tabs. So that I can click on the 'Date' tab in the tabpanel.
What I have tried : is by manipulating DOM like :
DOM.setElementAttribute(productTab.getElement(), "id", "Swagatika");
But that does not seem to be working. :(
Has anyone any idea if that is possible, if so How difficult is to add IDs.
Thanks in advance.
For testing using WebDriver, you're supposed to use a special module that <inherits name="com.google.gwt.user.Debug"/> (see "Renaming module" in the GWT DevGuide), and call ensureDebugId on your widgets.
In your case, after calling queryTabPanel.ensureDebugId("queryTabPanel"), the first tab would have an ID of gwt-debug-queryTabPanel-bar-tab1 (see TabPanel.html#onEnsureDebugId for the details).
In addition to the Debug flag you need to use TabLayoutPanel.getTabWidget(...) and use ensureDebugId on it like the following:
SimpleLayoutPanel newTabPanel = new SimpleLayoutPanel();
tabLayoutPanel.add(newTabPanel, "Date Tab");
tabLayoutPanel.getTabWidget(newTabPanel).ensureDebugId("MyDateTab");
Notice that setting the debug ID before adding the Widget to the tabLayoutPanel won't have any effect. Also make sure to use getTabWidget(..) and not getWidget(...).
I have to create a table in my wizard page and I want to create it using TableViewer. I'm using WindowBuilderPro for designing my wizard page. The TableViewer control is available in the palette of WindowBuilderPro but I'm not getting how to use it properly.
Has any body used the same?
Thanks a lot in advance!!
You have two ways of filling the TableViewer with contents (similar to TableViewers in JFace):
You can define a content provider and a label provider manually. A content provider has to return a set of Objects, that represent each line of the table; while the TableLabelProvider translates the returned objects to texts in the columns. The content and label providers are to set in the Properties box on the left. In this case, the resulting code should look like the following snippets: http://wiki.eclipse.org/JFaceSnippets#Snippet001TableViewer or http://wiki.eclipse.org/JFaceSnippets#Snippet007FullSelection.
On the other hand you could define JFace Data Bindings to fill the table with contents. In this case you have to define a corresponding binding, that returns the list of all contents; additionally you have to create a label provider, that works similar to the previous one.
There is also a way to fill the table content using a newer API then supported directly by WindowBuilder: you could create TableViewerColumns, and ColumnLabelProviders for each column, thus resulting in much nicer code for Label Providers (and also this API is newer, so it should be preferred for new JFace based code) - but in this case you have to create your code manually. See the JFace Table tutorial from Lars Vogel.
Additionally, if you don't know the JFace Viewer framework from before, I suggest reading the first few questions listed in the JFace FAQ to gain a better understanding of the ideas (and the tutorial from Lars Vogel is also nice for this reason).
I'm looking for a Combo(Viewer) in SWT/JFace which supports autocomplete / type-ahead, i.e. the user can enter a couple of characters and the drop down list should show all matching elements.
You can also check out the org.eclipse.jface.fieldassist.AutoCompleteField class. It's not a combo, just a text field, but it adds auto complete functionality as if it were a combo very easily. You can do something as simple as this:
Text textField = new Text(parentComposite, SWT.BORDER);
new AutoCompleteField(textField, new TextContentAdapter(), new String[]
{"autocomplete option 1", "autocomplete option 2"});
I don't think there is anything like this built into either Combo or ComboViewer.
As thehiatus suggests org.eclipse.jface.fieldassist.AutoCompleteField is probably the best place to look for this, however, there is support for Combos:
new AutoCompleteField(combo, new ComboContentAdapter(), new String[]
{"item0", "item1"});
You may be interested in Eclipse's "Content Assist" feature. You can see it in action when using the Eclipse IDE's Java editor. As you edit source code, you will sometimes see a drop-down menu with phrases that complete what you were typing. (Note that you can press Ctrl+Space to force the drop-down menu to be displayed.)
You can implement this in your own SWT/JFace application as well. The "Java Developer's Guide to Eclipse" has an sample application that implements Content Assist. The sample application is a SQL editor, and it is described in Chapter 26, "Building a Custom Text Editor with JFace Text." There's actually an online overview of the chapter here. The sample SQL editor project, com.ibm.jdg2e.editor.jfacetext.sql, can be found here.
On the other hand, if you want to create your own Combo widget and auto-populate it based on input that is being entered, then this might not be very applicable. I'm thinking the org.eclipse.jface.viewers.ComboViewer might be helpful (though I'm not positive).
Check out: http://sourceforge.net/projects/swtaddons/
I use it in my project (with a little tweak).
It's really dead easy to set this up.
As thanks to paz117's comment, thought I'd share the code to make this work:
String[] proposals = new String[controller.model().size()];
for (int i = 0; i < controller.model().size(); i++)
proposals[i] = controller.model().get(i).getAppropriateName();
comboViewer = new ComboViewer(parent, SWT.NONE);
comboViewer.setContentProvider(new ArrayContentProvider());
comboViewer.setLabelProvider(new AppropriateLabelProvider());
comboViewer.setInput(_controller.model());
// additionally, configure the comboViewer arbitrary
new AutoCompleteField(comboViewer.getCombo(), new ComboContentAdapter(), proposals);
The only minor nuisance is that you have to separately populate the model of ComboViewer and AutoCompleteField separately, but that can be at least automated via a static utility method or something similar.
As reference for future visitors, the AutocompleteComboInput (SWT Add-on), can also be a way to achieve this.
Code snippet for screenshot (refer to documentation link above for the code template):
import net.sf.swtaddons.autocomplete.combo.AutocompleteComboInput;
...
subjectCodeCombo = new Combo(tab3Composite, SWT.DROP_DOWN);
// other code modifying Combo appearance here...
// returns a String[] of items retrieved from database
String[] subjectCodeArray = dbQuery.subjectsToArray();
subjectCodeCombo.setItems(subjectCodeArray);
subjectCodeCombo.setText("- SELECT -");
new AutocompleteComboInput(subjectCodeCombo);
The add-on requires all JARs below to be added to the Library: (more info)
