View Full Version : TreeGrid performance and rendering problems

12 Jan 2010, 4:06 AM

I'm using GXT components in a new project development (not the smartest option, I know), and I'm getting some performance and rendering problems, the most worrisome in the TreeGrid:

1. Column labels become sticky for 4 seconds becoming a mess when you pass the mouse over the columns. Is this expected?

2. When scrolling the TreeGrid, the processor raises to 100% quickly and the row rendering delays for a while. I think this is not acceptable in a "simple" grid, There are some efficient tips for creating this? (I already test disabling the WidgetTreeGridCellRenderer).

3. Why can't select TreeGrid values to do a simple copy-past? Is this also expected? How can users do just a simple copy-paste?

Environment information:
Browsers: Firefox 3.5.7 and Internet Explorer 8
GXT version: 2.1.0
GWT Version: 2.0 (problems are the same with 1.7)
Hardware: Core 2 Duo T8300 with 3GB of RAM

I appreciate any help on these problems. Thanks.
