ComboBoxCellEditor List (Selection) [message #1232294]

Hello there,

I have some special question and found nothing about it, maybe someone could enlighten me.

I have a NatTable which provides some ComboBoxCellEditor(s) with a dynamic set of values. All is displayed well and behaves like designed i think.

My need is, that if the combo shell pops up there are all values ordered in one column and i may select them by clicking on them. But I would also like like to select them when the user clicks next to one, so that currently the item itself doesn't get the selection but the line of it does.

Clicking next to it will close the combo shell without an action yet.

How do i achiev this behaviour? You could compare it the the behaviour of some Excel sheet. (Sorry for this advertising but i would like to ensure the clearence of my possition.)

Thanks in advance

p

Do you have multiple selection via checkboxes or of what kind of combobox configuration are you talking?

This is the code where i define them. The provider only reimplements 'getValues()' which returns a list.

I have no multiple selection and no check boxes within these combo boxes.

configRegistry.registerConfigAttribute(CellConfigAttributes.CELL_PAINTER, new ComboBoxPainter(),
				DisplayMode.SELECT, COMBO_BOX_CONFIG_LABEL);
ComboBoxCellEditor comboBoxCellEditor = new ComboBoxCellEditor(new CSMComboBoxDataProvider(), 10);
configRegistry.registerConfigAttribute(EditConfigAttributes.CELL_EDITOR, comboBoxCellEditor,
				DisplayMode.SELECT, COMBO_BOX_EDITOR_CONFIG_LABEL);
configRegistry.registerConfigAttribute(EditConfigAttributes.CELL_EDITOR, comboBoxCellEditor, DisplayMode.EDIT,
				COMBO_BOX_EDITOR_CONFIG_LABEL);
configRegistry.registerConfigAttribute(EditConfigAttributes.CELL_EDITABLE_RULE, getEditRule(),
				DisplayMode.EDIT, COMBO_BOX_CONFIG_LABEL);

Well I would need to look at the behaviour. I always thought it behaves that way, but maybe something is wrong or the e is a special reason. Technically your only option to change the behaviour is to implement your own editor if the behaviour is as it is.

I was working a lot on the combo box to add support for multiple selection and stuff. So hopefully it works as designed. Will check tomorrow.

Ok, got it. In the current implementation the Table that builds the dropdown is in list mode. That means only TableItems are added. They keep their initial width and it is not possible to change this afterwards.

Modifying this to add a TableColumn and perform the necessery resize operations should solve that.

Could you please create a ticket so we are able to track the issue and the solution in Bugzilla?
