    Question RowEditor with CheckboxSelectionModel

    Hi,
    I have a GridPanel with a CheckboxSelectionModel and a RowEditor plugin.
    Is it possible to NOT activate the editor when checkboxes are clicked?
    It should be activated only when other fields of the row are clicked.

    Default

    You would have to override the onRowClick/onRowDblClick methods of RowEditor to first check if the checkbox was clicked and only call the original function when it wasn't.

    Thank you, Condor
    Something like this?.. (checkbox is the first column)
    Code:
    onRowClick: function(g, rowIndex, e)
    {
       var index = g.getView().findCellIndex(e.getTarget());
    
       if(index > 0)
          this.constructor.prototype.onRowClick.apply(this, arguments);
    
    }

    I would have used:
    Code:
    onRowClick: function(g, rowIndex, e){
      if (!e.getTarget('.x-grid3-row-checker')) {
        this.constructor.prototype.onRowClick.apply(this, arguments);
      }
    }
    but your code is good too.

    Solution Ext.ux.grid.RowEdit + Ext.grid.CheckboxSelectionModel + Ext.ux.grid.RowActions

    Aonde tem o lao for so colocar a verificao da funo:
    if(Ext.isFunction(c.getEditor){

    Aonde tem o lao for junto com o fields[i] adiciona:
    if(Ext.isFunction(c.getEditor) && fields[i]){

    Assim o rowEditor verifica se realmente uma coluna.

    English

    Where has the loop is placed so the verification of the function:
    if(Ext.isFunction(c.getEditor){

    Where has the loop along with the fields [i] adds:
    if(Ext.isFunction(c.getEditor) && fields[i]){

    So rowEditor checks whether it is really a column.


    var c = cm.getColumnAt(i);
    if(Ext.isFunction(c.getEditor) && fields[i]){
    val = this.preEditValue(record, cm.getDataIndex(i));
    f = fields[i];
    f.setValue(val);
    this.values[f.id] = Ext.isEmpty(val) ? '' : val;
    }
    if(Ext.isFunction(c.getEditor)){
    if(!cm.isHidden(i)){
    var dindex = cm.getDataIndex(i);
    if(!Ext.isEmpty(dindex)){
    var oldValue = r.data[dindex],
    value = this.postEditValue(fields[i].getValue(), oldValue, r, dindex);
    if(String(oldValue) !== String(value)){
    changes[dindex] = value;
    hasChange = true;
    }
    }
    }
    }
