Hi All,
I am using the Gallery Widget for displaying the list of
contents(folders and files) just like a Windows explorer kind of thing...
If I select a particular folder, the contents of that folder is getting
displayed ,the problem is it is not clearing the selection even after I
placed deselectAll() method;
Here is the code...for constructGallery on click of folder.
private void constructGallery(CustomerModel domain)
{
gallery.clearAll();
gallery.deselectAll();
i1 = new GalleryItem(gallery, SWT.NONE);
i1.setText(domain.toString());
if (domain.child != null)
{
for (int i = 0; i < domain.child.size(); i++)
{
GalleryItem i2 = new GalleryItem(i1, SWT.NONE);
// Your image here
i2.setImage(Util.getImageRegistry().get("galleryImage"));
i2.setText(domain.child.get(i).toString());
gallery.deselectAll();
}
}
gallery.deselectAll();
}
Thanks in advance,
Swetha

Hi Swetha,
This seems to be a bug. I took a quick look in the gallery code but I
couldn't find the reason why it is not clearing the selection.
Please try this and tell me if this fix the problem :
- add i1.deselectAll() and i2.deselectAll()
- add gallery.redraw() to force update
(this should be done automatically by the widget).
If it still doesn't work, please fill a bug report in bugzilla and
include a snippet if you can.
Thanks,

Hi,
Please double check you code, and add debug output to see if deselectAll
or constructGallery are really called.
deselectAll is working for me.

Hi,
Ok, I think I understand the problem :
Item selection is based on Windows explorer behavior. And in some cases,
an item becomes selected on mouseup event.
So when you double click on an item, the double click event is raised
first, and you replace the content of the gallery.
Then the mouse up event occurs and selects the item which is under the
mouse.
I'm going to fix this asap.

Item... deselectAll() is there on Gallery Object.Please give me an idea
how to solve this

Hi,
Thanks for the reply... Both constructGallery(domain) and deselectAll()
are getting called...Actually the logic of the required functionality is
achieved thru this constructGallery method only...
Everything is working fine.. except this selection...
Let me say my problem once gain,
Suppose there 10 folders which are arranged in 5 rows and 2 cols in
gallery widget..
If I double click on second row and first col folder(which contains again
8 child folders), will display the 8 folders in 4 rows and 2 cols..here is
the folder...As I selected the second row and first col folder, the folder
which is in that place(2nd row 1st col) is showing as selected....which I
don't want..
Thanks,
Swetha

Hi,
Thanks .. Actually for my widget I don't need mouseUp event, for the
time being I commented that mouseUp method and its working fine...
Please let us know once it is fixed.
