Change the state of a checkboxColumn

[ales]

Hi,

I have a grid in which my first column is a CheckColumn.

In one case, I want that all my checkboxes are slectable, and in an other case, (when I click on a button) I want that all my checkboxes are disabled.

How can I do this ?
I have not found a solution to do that.

Thanks.

If you are using Ext.grid.CheckColumn component

var checkColumn = new Ext.grid.CheckColumn({
    ...
    //listen your mouse down event
    onMouseDown : function(e, t){
            if(condition1) {
                //return false to stop the checking
                return false;
            }
    }
});

Try this, this will fix all the scenarios. Play with it according to your needs.

onMouseDown : function(e, t){
    if(condition1) {
        return false;
    }
    //else follow the normal routine
    if(t.className && t.className.indexOf('x-grid3-cc-'+this.id) != -1){
        e.stopEvent();
        var index = this.grid.getView().findRowIndex(t);
        var record = this.grid.store.getAt(index);
        record.set(this.dataIndex, !record.data[this.dataIndex]);
    }
}

Thank you.

But this is PHP code. Is it the same way in Java ?

Oh you are asking for GWT, try a similar thing in GWT. The code sample is for ExtJS/Sancha

Yes, I'm asking for GXT

I will try to adapt it.
