Hello,
I have a table viewer and a vertical scrollbar. If I have to scroll
vertical and come out of my window size with the vertical scrolling, the
table header is cutting of and dispose. That means, the table header
doesn't show.
It is a bug in RAP or there is a solution for this problem?
Thanks,
kristin

The table viewer isn't in a ScrolledComposite.
Here is a code snippet of my table viewer.
public static final String[] PROCESS_STATUS_ITEMS = {"jbpmInstanceId",
"tokenId","processInstanceId","parentTokenId",
"superProcessTokenId","subProcessTokenId","status","processName ",
"patchVersion","phase","phaseTimestamp","state","stateTimestamp ",
"additionalData","replacementProcessInstanceId","techId", "customerId",
"ccdId","contractId","timerInfo","lastEventTimestamp", "lastEventType",
"failedJobInfo"
};

Sorry, the post was not ready.
So, here is the complete code snippet.
public static final String[] PROCESS_STATUS_ITEMS =
{"jbpmInstanceId","tokenId","processInstanceId","parentTokenId ",
"superProcessTokenId","subProcessTokenId","status","processName ",
"patchVersion","phase","phaseTimestamp","state","stateTimestamp ",
"additionalData","replacementProcessInstanceId","techId", "customerId",
"ccdId","contractId","timerInfo","lastEventTimestamp", "lastEventType",
"failedJobInfo"};
private class ViewLabelProvider
extends LabelProvider
implements ITableLabelProvider
{
public Image getColumnImage( Object element, int columnIndex ) {
return null;
}
public String getColumnText( Object element, int columnIndex ) {
String[] row = ( String[] )element;
String result = row[ columnIndex ];
return result;
}
}
private class ViewContentProvider implements IStructuredContentProvider {
public Object[] getElements( Object inputElement ) {
int s = 10;
Object[] rows = new Object[s];
for (int i = 0; i < s; i++) {
String[] row = new String[ PROCESS_STATUS_ITEMS.length ];
for( int j = 0; j < PROCESS_STATUS_ITEMS.length; j++ ) {
row[j] = "test" + i;
}
rows[i] = row ;
}
return rows;
}
public void dispose() {
}
public void inputChanged( Viewer viewer, Object oldInput,
Object newInput ) {
}
}
private String[] initColumnProperties( final Table table ) {
String[] result = new String[ PROCESS_STATUS_ITEMS.length ];
for( int i = 0; i < PROCESS_STATUS_ITEMS.length; i++ ) {
tableColumn = new TableColumn( table, SWT.CENTER);
result[ i ] = PROCESS_STATUS_ITEMS[i] ;
tableColumn.setText( result[ i ] );
tableColumn.setWidth(170);
}
return result;
}
public void createPartControl(Composite parent) {
tableViewer = new TableViewer( parent, SWT.MULTI | SWT.V_SCROLL
| SWT.H_SCROLL);
tableViewer.setContentProvider( new ViewContentProvider() );
tableViewer.setLabelProvider( new ViewLabelProvider() );
final Table table = tableViewer.getTable();
tableViewer.setColumnProperties( initColumnProperties( table ) );
tableViewer.setInput(this);
tableViewer.getTable().setHeaderVisible( true );
tableViewer.getTable().setLinesVisible(true);
}

Hi Kristin,
your snippet is running fine. What I do not understand where is the
vertical scrollbar? How to make the header to cut off? Any steps to
reproduce it?
Best,
Ivan
