problem of KONtx.control.MetadataDisplay

Hi everyone,

Is there any method similar to KONtx.control.MetadataDisplay, which can be used in grid displays to show a image or some text related to each cell when an individual cell is selected?

Thanks

  • Just add an onFocus event to the cell and hook that to the display that you want.

    But If I want to focus on a cell and show the pictures or text in another container, can it be realized?

    I've tried many times but doesn't work

    Can you just give me some exemples?

  • you need to pass a reference to the object you are trying to update with the information for the cell.

    CODE
    createView: function() {
          this.mydisplay = new KONtx.elements.Container();
           //put whatever you want in the container.
          // I am assuming a function called setTitle
          this.mygridy = new KONtx.elements.Grid();
    }

    updateView: fucntion() {
           this.mydataset = [{title:"my item 1",thedisplay:this.mydisplay},{title:"my item 2",thedisplay:this.mydisplay}]
           this.mygrid.changeDataset(this.mydataset, this.mydataset.length < 1);
    }

    _cellCreator: function() {
                 var cell = new KONtx.control.GridCell({
                       events: {
                                 onFocus: function () { this.info.thedisplay.setTitle(this.info.title); },   //Set the title on focus
                                 onBlur: function () {this.info.thedisplay.setTitle(""); },  //Clear the title on removed focus
                                      }
                                    return cell;
            },

    _cellUpdater: function(cell, dataitem) {
                  cell.info = dataitem;
            },
