The code in TreePanel throws sporadic exceptions when dragging and dropping tree nodes from one parent to another, due to the findChildren() method assuming the call to findNode() always returns a...

Reloading the entire store is not an efficient way to handle this, we should be able to update the model contained by the TreeNode via an API such as TreePanel.updateTreeNode(ModelData model) or...

Calling store.update(model) does render the new value on the TreeNode label but it does not update the model held onto by the TreeNode , so you end up with a stale model in the TreeNode if you've...

I've run into another use case where I simply cannot update the model contained by a TreeNode in a TreePanel. Could you please tell me if there's a way to do this? I don't see a public method to do...

[by ccocco_dw]

Can you explain how the TreeNode would get updated in this case?

Hi, it would be extremely difficult to post a full working copy as the code I'm writing is integrated into a fairly complex application. I will post the code specific to the drag and drop TreePanel....

If you perform a drag and drop in a TreePanel, capture the drop event, modify the model associated with the dragged TreeNode (e.g. adjust the parent ID attribute of the model to reflect the new...

Could the GXT Team please comment on this question? Thanks!

I have a remote TreePanel that allows a user to create a new parent or leaf via a button. When this button is initiated, a new object model is created and returned via RPC. Once I have the new...

Hi, did you ever get a resolution to this issue? I cannot find an easy way to add a custom renderer to a TreePanel either but I need one for the same reason as you, to add additional buttons to a...

I need to provide a custom renderer for Tree Nodes in a TreePanel but I don't see support for this other than to override the TreePanelView.getTemplate() method and append additional HTML elements to...

What is the recommended way to add a row to a local TreeGrid once it's been rendered (e.g. via an Add button)? Is doing an add/insert into the TreeStore sufficient or do I need to call...

[by ccocco_dw]

Hi, the extended RowExpander class works well if you create the custom component used in the makePanel() method every time a row is expanded. But if you attempt to create it once and return it in...

When a cell is selected in an editable grid with a RowEditor, it puts the entire row into edit mode. If one of the columns is a CheckBoxSelectionModel, selecting a checkbox in that column puts the...

There seems to be a bug in the GroupingView.doRender() method that causes duplicate groups to be created by the Group By option using with a Grid. If grouping by column X, where rows 1-3 contain the...

The following seems to work although it feels like a work-around. If there's a more elegant way to do this, please let me know. Thanks!

Yes, we have lots of types of grids in our application (e.g. local, remote, paging, non-paging) and they have local or remote sorting in various instances. Is there a way to disable sorting when...

[by ccocco_dw]

When using a local paging or non-paging grid without any sort in affect, inserting a model into the grid store at index 0 always adds it to the end of the grid. Stepping through the...

RowEditor.getTargetColumnIndex() intermittently returns null when trying to get the header cell for a visible column (grid.getView().getHeaderCell(i)) when editing starts, causing an exception to be...

Actually, Component.setToolTip() should call Component.getToolTip() to create a new ToolTip and this would allow subclasses of Component widgets to override getToolTip() and return a custom version...

[by ccocco_dw]

I can't use QuickTip as I need to display a ContentPanel with widgets in it, but I can probably use the getCell() call within a mouse over event to get the cell that's being hovered over and then...

[by ccocco_dw]

How would I display a custom tooltip (e.g. ContentPanel) over a grid cell when the mouse hovers over it? It has to be dynamic as each cell can have different data to display in the tooltip. I need...

Hi, how would I animate (e.g. Slide In/Slide Out) adding a panel to the viewport? The showcase demonstrates a sliding panel that already exists within a container using a button to trigger it, but...

Thanks Sven, I agree that calling Component.setToolTip(ToolTipConfig myCustomToolTipConfig) will allow me to override the default usage of the GXT ToolTipConfig in Component.setToolTip(String text). ...
