javafx - Select first/last clears anchor information - MultipleSelectionModel -
i have table table.getselectionmodel().setselectionmode(selectionmode.multiple);. need implement go last/first row of tableview. used table.scrollto(ind); table.getselectionmodel().clearandselect(ind). scroll first row , select it. if try select numerous rows (using mouse right button + shift) doesn't select range of rows between first row , 1 pressed set anchor @ selected row.
what i've observed far:
- from pseudoclass css information. first row selected,focused - exprected.
table.getselectionmodel().selectedindexproperty() table.getselectionmodel().getselectedindices()shows 0 , [0] respective - expected- row not selected - table no longer focused got grey not blue row. if call
table.requestfocus()@ time , useplatformutil.runlater()doesn't change anything. assume has nothing table focus.
any ideas howto (from code) select first row , make such situation after pressing mouse button on other row shift got multiple selection?
sample application. see createselectioncontrol() -> button("|<")
