Grids

Hello BIRT community,

I am trying to copy existing grid and paste that grid in a another global grid programmaticaly. But I always get errors. I have tried to use the copy method IDesignElement copy() but then i get GridItem instead of GridHandle. Beside that the addElement method needs slotId.

Then I found some post here on the forum about using the CopyUtil class. Using that class I can copy and paste the element but the problem ist also the slotId. I always get error that on that slot adding is not allowed.

"The copy is not allowed to be pasted into the Report Design's slot 0 because it is invalid."

The example here: http://eclipsesrc.appspot.com/jsrcs/org.eclipse.birt.report.model.tests/test/org/eclipse/birt/report/model/core/DesignElementCopyPropertyToTest.java.html
only shows how to copy some property of the grid and add the new grid to the body.

It would be nice to know how to copy and paste grid into another grid programmaticaly via the BIRT API.

Thank you in advance.

Does the getSlotID() gives Flags that are meaning if this SlotHandle is row or column?
1 for rows
0 for columns

You can always get the handle like:
item.copy().getHandle(null);

Where are you trying to copy it to?

Hi Jason, 
 
I want it to copy it into another grid wich I have it as GridHandle like: 
<pre class='_prettyXprint _lang-auto _linenums:0'>
GridHandle outerGridHandle = (GridHandle) designHandle.findElement("myOuterGrid");
GridHandle innerGridHandle = (GridHandle) designHandle.findElement("myInnerGrid");
GridHandle copyGridHandle = (GridHandle) innerGridHandle.copy().getHandle(null);
try {
// what should I use as property instead of null?
outerGridHandle.paste(null, copyGridHandle, 0);
} catch (SemanticException e) {
e.printStackTrace();
}
</pre>
 
Beside that is this the right approach?

Do you really want to copy or move? I did this in script but the api should be similar:

var mygridouter = reportContext.getDesignHandle().findElement("mygridouter");
var mygridinner = reportContext.getDesignHandle().findElement("mygridinner");

var cellhan = mygridouter.getCell(2,2);
//to move it
//mygridinner.moveTo(cellhan, 0/*cellhan.getContent()*/);

//to copy it
var cpy = mygridinner.copy().getHandle(reportContext.getDesignHandle().getModule( ));
reportContext.getDesignHandle().rename(cpy);
cellhan.getContent().add(cpy);

Thank you Jason for the hint. 
I have tested the copy method and the add function and it works fine. 
I hope the move method works the same way. didn't have some scenario to check that now. 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>
//designHandle is object type ReportDesignHandle

GridHandle outerGridHandle = (GridHandle) designHandle.findElement("myOuterGrid");
CellHandle outerGridHandleCell = outerGridHandle.getCell(0, 0);

GridHandle innerGridHandle = (GridHandle) designHandle.findElement("myInnerGrid");
GridHandle copyGridHandle = (GridHandle) innerGridHandle.copy().getHandle(designHandle.getModule());

// move
// it had copiled but i havent test the move method. i think this should be the right syntax
try {
innerGridHandle.moveTo(outerGridHandleCell , outerGridHandleCell .getContent().getSlotID());
} catch (SemanticException e1) {
e1.printStackTrace();
}

// copy
// getDesignHandle is deprecated but still valid and can be used
copyGridHandle.getDesignHandle().rename(copyGridHandle);
try {
// adding at the fisr position for example
outerGridHandleCell.getContent().add(copyGridHandle, 0);
} catch (ContentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (NameException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
</pre>
