I have a org.eclipse.ui.part.ViewPart in my eclipse plugin. The Viewpart has a org.eclipse.jface.viewers.TreeViewer. Now i want something like a caption over the tree viewer, to provide information of what data is shown in the tree. If caption doesn't describe my need, i want a line of text above the tree viewer to show some text.
shows my current view
red line in this image shows where i want my line of text
Thanks in advance.
If you mean you just want a line of text above the TreeViewer the viewer itself does not support this. Instead just use a separate Label control to contain the text.
Something like:
#Override
public void createPartControl(final Composite parent)
{
Composite container = new Composite(parent, SWT.NONE);
container.setLayout(new GridLayout());
Label label = new Label(container, SWT.LEAD);
label.setText("Caption");
TreeViewer viewer = new TreeViewer(container);
viewer.getTree().setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
....
Note that you need to use a Composite to contain the multiple controls.

I'm setting the visibility of a PdfFormField to HIDDEN using the setVisibility() method with parameter PdfFormField.HIDDEN. Still, on flattening it, the field does not hide. Below is the code to do so.
File file = new File("path to PDF file");
baos = new ByteArrayOutputStream();
pdfDoc = new PdfDocument(new PdfReader(file.getAbsolutePath()), new PdfWriter("path to flattened PDF file"));
//This function removes all the permissions.
removePdfPermissions();
form = PdfAcroForm.getAcroForm(pdfDoc, true);
fields = form.getFormFields();
fields.get("HumanSubjectsText").setVisibility(PdfFormField.HIDDEN);
fields.get("HumanSubjects").setVisibility(PdfFormField.HIDDEN);
form.flattenFields();
pdfDoc.close();
Setting the values of the fields to empty string "" is a workaround, but not the proper way.
The fields "HumanSubjects" and "HumanSubjectsText" correspond to a checkbox and its correspond text on page 2. (Human Subjects)

The fields could not be hidden using iText library. In contrast to Bruno's comment, one of the methods from iText library worked well, the setValue(). I'm not quite sure why the setVisibility() fails.
However, I was able to hide the field using Master PDF editor tool. I've attached a screenshot of this tool, where you can change the visibility for a form field from the General tab.
An observation: In the com.itextpdf.forms.fields.PdfFormField some of the constants defined are as follows:
public static final int HIDDEN = 1;
public static final int VISIBLE_BUT_DOES_NOT_PRINT = 2;
public static final int HIDDEN_BUT_PRINTABLE = 3;
public static final int VISIBLE = 4;
The Master PDF editor also has similar options to hide a field. Please refer to the attached screenshot.
NOTE: My requirement was just to simply hide the field. It could be achieved programmatically by using a library like iText or with some PDF editor tool.
I have to fill PDF form with some data. This form contains a few tables with "Add" button which adds new row with inputs to this table, for example to "FOREIGN PATENT DOCUMENTS".
I need to "click" this button in my code using iText a few times, add necessary rows, get input names there and fill them. How can I do this with iText? Could anybody provide me a code example?
My PDF file with form https://drive.google.com/open?id=0BwtWU1543EbTQ3A3b2dZcW9qYk0
This file is predefined and I can't regenerate it.
You don't "click" a button programmatically. You just provide the data that is necessary, and the form will adapt.
See the FillXFA example. We have a purchase_order.pdf that looks like this:
This document has an "Add item" button to add more line items (which results in creating more pages if necessary). That button only makes sense if there's a GUI, but when you fill out the form programmatically, there aren't any buttons to push. You just provide the XML with the data (e.g. data.xml), like this:
public void manipulatePdf(String src, String dest)
throws IOException, DocumentException {
PdfReader reader = new PdfReader(src);
PdfStamper stamper = new PdfStamper(reader,
new FileOutputStream(dest));
AcroFields form = stamper.getAcroFields();
XfaForm xfa = form.getXfa();
xfa.fillXfaForm(new FileInputStream(XML));
stamper.close();
reader.close();
}
The result looks like this: purchase_order_filled.pdf
As you can see, multiple lines were added, without pushing any button.
Important: I see that you have a hybrid document. I think you should make it a pure XFA form. This code won't work if you keep the AcroForm fields.
We have a dijit.Tree that indicates a node type by using an icon. The icon is a unique indicator that tells the person this node is a "book" or a "DVD" or a "magazine" for example.
dijit renders the icon as a background image in CSS which we know screen readers do not see.
I tried overriding the getTooltip method to provide a tooltip saying "book" or "DVD". It successfully adds the "title" attribute to the "dijitTreeRow". If I mouse over the node, I see the text. This is not ever focused on when the user moves down to get from one node to the next.
When navigating the tree, the up and down arrows traverse the nodes. The span with the visible text is focused on and that string is read. You can see the dotted line focus as well as hear this with JAWS in the most basic of examples: https://dojotoolkit.org/reference-guide/1.10/dijit/Tree.html
What I have not been able to figure out is how to create an indicator that the screen reader will pick up on that will read "Book" alongside "The Great Gatsby".
Does anyone have any tips on how they made this dijit widget accessible for the screen reader when the images are an indicator that should be heard by the blind user?
The tree supports HTML labels, via setting the labelType property on the model you give it.
Assuming you don't want to change the store data (or override the getLabel method), you can reimplement dijit/Tree.getLabel and produce the HTML label, and wrap it with a span with an aria-label.
(code lifted from the dijit.Tree reference).
var myModel = new ObjectStoreModel({
store: myStore,
labelType: "html", // Hack to tell the tree node to render as HTML
query: {id: 'world'}
});
var tree = new Tree({
model: myModel,
getLabel: function(item) {
var label = this.model.getLabel(item);
// dojo.string
return dstring.substitute("<span aria-label='dvd ${0}'>${0}</span>", [label]);
}
});
If your data might contain HTML-ish characters that you don't want to render, escape the characters in getLabel too.
I have a Master-Detail set up with 2 grids. On the master grid, I have the ShowOnlyPredefinedDetails option set to false.
This means that I see a little + sign that allows me to expand the details of the detail grid (in the master grid). I would like to rename
some columns in that section as well as hide certain columns. I'm using VB.NET How do I go about this. See image.
You can accomplish this by using the grid control ViewRegistered event, from there you can modify the columns in that grid view that have columns within them that you want to modify, rename, or remove. Here is an example, I hope that it helps:
private void myGridControl_ViewRegistered(object sender, DevExpress.XtraGrid.ViewOperationEventArgs e)
{
if (e != null)
{
if (e.View != null)
{
//Inside of this statement you can adjust, add, and modify all of the columns inside of that grid that appears when you click on the +
(e.View as GridView).Columns["myHiddenColumn"].Visible = false;
(e.View as GridView).Columns.Add(new GridColumn() { Name = "AddColumn", Caption = "Name To Display", Visible = true, FieldName = "DataField"});
(e.View as GridView).Columns["DataField"].OptionsColumn.AllowEdit = false;
(e.View as GridView).Columns["DataField"].OptionsColumn.AllowFocus = false;
(e.View as GridView).Columns["DataField"].OptionsColumn.ReadOnly = true;
}
}
}
I think all you need to do is create a second grid view for your details. If you haven't already done this, do the following:
In your grid designer, click "Retrieve Details" if you have not already done so. This will cause the designer to recognize that you have a second level in your bound object:
Once you see the second layer, now you need a new grid view for it. Click on "Click here to change view" and select "Create a new view" and pick "GridView."
Now you will see both grid views from the designer, and clicking on one or the other will change the context of the menus to the left:
For example, if you have gridView2 selected, when you click on the "Layout" menu, it will show the current layout for your detail grid rather than the master grid. From here, you can remove or add columns as you see fit. Likewise, from the "Columns" menu you will see the new columns (you may have to add them to the view by dragging them over), and you can change the Caption property to change the text of the title.
I suggest you use the Data Annotation attributes with properties of your data-classes to declare how you data should be displayed in GridControl:
To skip column generation for the specific property you can mark this property with the <DisplayAttribute(AutoGenerateField := false)> declaration.
To prevent column from displaying you can mark this property with the <DisplayAttribute(Order := -1)> declaration. Later, user can show this column via Column Chooser UI.
To specify the column caption use the <DisplayAttribute(Name := "YOUR CAPTION")> declaration.
You can also control filtering/editing/formatting and validation capabilities.

I’m using eclipse rcp forms ,
I'm trying to set an Image using
form.setImage()
merely it sets image to the left of form text. How can i place an image towards top right corner of the form title text.
As shown in below pic(image is the default overview tab of any RCP application)
From the above pic I understand that the images/widgets are placed beside the Form text(apologies if I’m wrong).
As a workaround I tried placing a composite in the form head, but I believe that form head comes after form title level(if we consider form title as 1st row, then form head appears as 2nd row)
Composite composite = formToolkit.createComposite(form.getHead(), SWT.NONE);
form.setHeadClient(composite);
formToolkit.paintBordersFor(composite);
composite.setLayout(new GridLayout(2, false));
In this fashion i attempted to place components to the composite but anyways I don't get the desired style as shown in the image.
How to place an image to the top right of the form title
You cannot set images to the right corner. What you see in the attached image is a toolbar with some IContributionItem's
To create something you have to override org.eclipse.ui.forms.editor.SharedHeaderFormEditor.createHeaderContents(IManagedForm) with something like the following:
#Override
protected void createHeaderContents(final IManagedForm headerForm) {
headerForm.getForm().setText("EditorTitle");
headerForm.getForm().setImage(myLeftImage);
headerForm.getToolkit().decorateFormHeading(
headerForm2.getForm().getForm());
Action action = new Action("Do something") {
#Override
public ImageDescriptor getImageDescriptor() {
return imageDescriptorOfRightImage;
}
};
headerForm.getForm().getToolBarManager().add(action);
headerForm.getForm().getToolBarManager().update(true);
}
