Hi i am trying to develop a GWT web application for teachers. On the one of my page is showing student information. Page has DockLayoutPanel , on the west side there is a CellList and on the center there is flextable

  • CellList has content info about studuents (Name , surname , id)
  • FlexTable has detailed info about students , on each row there is one widget for one student
  • each celllist and flextable is loaded with same data , one is showing short info other detailed.

My question is flextable is inside of scroll panel , is it posible to select record in the cell list which is displaying on the flextable(scroll panel) i can get record id from both sides.

i found the solution :

  • firstly i put scroll handler to my flextables scroll panel

  • then i wrote a method for handler that checks which widget is showing in scroll panel (How to know which element is being displayed in GWT ScrollPanel) btw i have overloaded scrollpanel class that that takes widger and item id

    private class CustomScrollPanel extends ScrollPanel{ private long id; CustomScrollPanel(long id,ScrollPanel sp){ this.id = id; setWidget(sp); } public long getId(){ return id; } }

  • Now i have id which is showing on flextable , lastly i wrote a method that checks CellList with ids , when it founds the id in cellists visible items, selects its cell with selection model of celllist
