Re: [qooxdoo-devel] How can I add new items to a table

[Alex D.]

Hi, yes, you are right. i have already discussed this(see mailing list archives). One possible solution for this is to leave one empty row in the table(i know this looks not really pretty)  or use this patch(see attachment). Cheers alex.d Hi, This technique doesn't work when deleting the last row of a table. An exception is received and the table doesn't repaint. :-( dperez wrote: Hi all, It couldn't be simpler. I modify the data array and set the table model data again to the same array. dperez wrote: Hi, I've seen that the TableModel class has methods for changing existing data, but what about adding new items and removing existing ones? I have tried to modify directly the array of data, but the table gets confused. Thanks in advance for any help. Regards, David
