I want the rows of nattable to be single-select only.
Now, multi-selection is possible using ctrl or shift. How do I make single-selection possible?
I would be very grateful if you could leave an answer to a question
If you want to support row selection only, you need to configure the RowSelectionModel to set the multipleSelectionAllowed flag to false and set it as SelectionModel to the SelectionLayer.
Have a look at our examples application to get an idea how this can be done.

is it possible to configure agGrid grouping so that it behaves like an accordion i.e. only one group can be expanded and when opening new group previously opened is closed?
Not sure if this answers your question, but I am sure this might be the only direction you'll have.
There is a method provided on gridApi - onGroupExpandedOrCollapsed
So I think (again, need to check) that this function would be called as its name suggests, and you can collapse the other rows (whichever is opened) and achieve your functionality.
Be cautious while using this as there is comment given by ag-grid
we don't really want the user calling this if one one rowNode was
expanded, instead they should be calling rowNode.setExpanded(boolean)
- this way we do a 'keepRenderedRows=false' so that the whole grid gets refreshed again - otherwise the row with the rowNodes that were
changed won't get updated, and thus the expand icon in the group cell
won't get 'opened' or 'closed'.
I'm working with Fiori elements, and in the ObjectPage I want to display a table inside a section. For this table I have a column as a boolean type.
Is it possible to manage this column as a checkbox by annotation, or some other way? If so, how?
I am not sure why it should not be possible. Since a checkbox basically has two states, it should be able to handle the boolean variables very well. Care to explain more about what exactly you want to achieve?
When using Fiori Elements currently a boolean value is displayed as text.
Expect you are in edit mode - then a checkbox is rendered.
So, the answer is 'No' for display mode and 'yes' (by default) for edit mode.
Does anyone know if its possible to select multiple items on a QTreeWidget and how to go about enabling the multiple selection?
All the items I want to be selectable are top level QTreeWidgetItems and all their children are set to be disabled (i.e QTreeWidgetItem.setDisabled(True) )
It is, you'll want to call setSelectionMode during init to enable QAbstractItemView::MultiSelection. QTreeView/QTreeWidget inherit QAbstractItemView, so it is available.
Then to disable the items, just hook on to QTreeWidgets.itemSelectionChanged() signal.
I think below will help:
youQTreeWidget.setSelectionMode(QGui.QAbstractView.MultiSelection)
I've got a CellTable with a column rendered with a CheckboxCell. I want to check the boxes to select the rows.
The default behavior with CheckboxCell(false, false) is tantalizingly close to my goal - selecting a row checks the checkbox, and de-selecting a row unchecks the checkbox. However, if I click a checkbox, it unselects any already-selected rows. Even worse, when I uncheck a checkbox, the row is not deselected. Argh!
I'm looking at coding my own cell now (or messing with the SelectionModel?), but this seems like behavior Google might have been trying for. I've tried every permutation of values in the constructor, to no avail. Is there a simple override I can add to finally make my dream... a reality?
You know how you can search for 30 minutes, and then 20 seconds after you post your question you find your answer?
Well, it turns out that to unleash the power of the CheckboxCell, you need to pass a Handler that is equipped to deal with the complexities of the situation. Try
setSelectionModel(selectionModel, DefaultSelectionEventManager.<T> createCheckboxManager());
with your MultiSelectionModel selectionModel - the selectionModel itself is not enough!
I have a data-grid and three column in it. one column is type of DataGridViewComboBoxCell, three items are in this grid combo box, now i have to invoke selection index changed event to change value according to combo value change in grid.
also help me to make a new event ....
please help...
thanks
I really can't understand your question.
But maybe these informations can help:
A ComboBoxColumn has always two kinds of controls. A presenting one (in most cases a label) which is individually for each row. And a editing one that will be shared for the whole column. So take a look into this documentation and the IDataGridViewEditingControl Interface.
Maybe these will give you a starting point on how to solve your problem.
In the Load event for the form, you need to get the cell that you want to add the handler to and cast it as a regular combo box. You can then add the event handler on SelectedIndexChanged, but it must be done programmatically, and depending on the language you are using.
