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

Hi Kristin,

you have a vertical scrollbar of the page with RAP application? Or
TableViewer is in ScrollComposite? Can you provide a simple snippet that
reproduce it?

Best,
Ivan

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

Hi,

ok. I have two parts in my application window. One part is the table
viewer and another part is a detail view. Could you try to make the window
of the table viewer to a minimum size? So that you have always a vertical
scrollbar.

Hi Kristin,

I've tried to reproduce it with the Workbench Demo without success.
There is a table in "View IV" with horizontal and vertical scrollbars.
Scrolling the table vertically does not move the table header at all -
only the table data are scrolled. Tested on Windows Vista, FF 3.0.10,
IE8 and Chrome 2.0 with RAP from CVS HEAD. Which version of RAP do you
use? What is your environment - OS, browser?

Best,
Ivan

Kristin,

feel free to file a bugzilla about this issue. It seems that it is
environment (Linux + Firefox 2) dependent issue as I can't reproduce it
on windows.

Best,
Ivan

Hello Ivan,

I tested the RAP Demo project and my RAP application on other OS-systems
(Windows Xp, Ubuntu 8.04) and it works.
I updated my Mozilla Firefox to version 3.0.10 and I have the same problem
that the table header cut off. It seems that this problem isn't a special
Linux and no browser problem.
Therefore I don't open a bug.

Kristin,

could you provide a screenshot that shows the problem? I have no clear
idea about the problem you describe. If you're sure that this is a bug,
feel free to file it in our bugzilla, see:

Hello,

I updated my RAP to the new version and I have no problem with the table
header when I scroll vertical. So, it is none bug.
