[Pharo-dev] FTs now support single and multi-cells selection

June 5, 2017

      Hello everyone, 
You can now select single or multiple cells in FTs, for that you need to set
the selectionMode to #column
I made a short video to illustrate that: https://vimeo.com/220251050

There are a few things to note here: 
-	The default selection mode is set to #row.
-	A reference to the fasttable needs to be passed the FTCellMorphs in the
DataSource.
-	For multi-cell selection, the command key stroke on macOS is mapped to the
Alt gr key in Windows, this doesn't seem right but this is what the "event
commandKeyPressed" returns.
You can find an example in the Examples sub package in the
Morphic-Widgets-Fasttable package: âexampleTable6â

|table ds|
ds:=FTSampleDataSource new:10.
table := FTTableMorph new
		extent: 500@500;
		selectionMode: #column;
		addColumn: (FTColumn id: 'column1');
		addColumn: (FTColumn id: 'column2');
		addColumn: (FTColumn id: 'column3');		
		dataSource: ds;
		selectRowIndex: 1;
		showFirstRowSelection;	
		beMultipleSelection;
		onAnnouncement: FTSelectionChanged 
			do: [ :ann | ('rows selected: ', (ann newSelectedRowIndexes asString))
crLog ];
		onAnnouncement: FTCellStrongSelectionChanged 
			do: [ :ann | |index morph ed |
				index := ann selectedCellIndex.
				morph := table visibleCellMorphAtIndex: index.
				ed := RubFloatingEditorBuilder new
					customizeEditorWith: [ :editor | 
						editor scrollbarsShowNever.
						editor bounds: (morph bounds insetBy: (Margin left: -2 top: 0 right: 0
bottom: 0  ))
					];
				withEditedContentsDo: [ :editedContents | 
					(ds elements at: index first) instVarAt:index second put:
editedContents asString.
					table refresh].
				ed openEditorWithContents: ((ds elements at: index first)  instVarAt:
index second).
		];
		yourself.
		table openInWindow.
