3.0 beta 2

Suggestion for feature - cell marker

Alex

A interesting feature may be to have a marker of some kind in the corner of a grid cell to show the user that there is a further info' associated with the cell: this may be availability of a mouseover tooltip, availability of an onContextmenu or something else.

What I'm thinking of is the like the comment cell marker in MS Excel.

That should not be very difficult -

<style>

.aw-item-indicator {
    display: none; /* hidden by default */
    position: absolute;
    overflow: hidden;
    right: 2px;
    top: 2px;
    width: 8px;
    height: 8px;
    background: red;
    cursor: pointer;
}

.aw-indicator-visible .aw-item-indicator {
    display: block; /* visible */
}

</style>
<script>

// new cell template class
var MyTemplate = AW.Templates.Text.subclass();

MyTemplate.create = function(){

    var obj = this.prototype;

    // hides/shows indicator depending on cell/indicator poperty
    obj.setClass("indicator", function(){
        return this.getControlProperty("indicator") ? "visible" : "hidden";
    });

    // indicator span element
    var indicator = new AW.HTML.SPAN;
    indicator.setClass("item", "indicator");
    indicator.setEvent("onclick", function(){
        this.raiseEvent("onCellIndicatorClicked");
    });
    obj.setContent("box/indicator", indicator);
}

    var obj = new AW.UI.Grid;
    obj.setCellData(function(col, row){return col + "." + row});
    obj.setHeaderText("header");

    obj.setColumnCount(10);
    obj.setRowCount(10);

    // new cell property hides/shows indicator sign
    obj.defineCellProperty("indicator", false);

    // show for cell 1-1
    obj.setCellIndicator(true, 1, 1);

    // our new template for col-1
    obj.setCellTemplate(new MyTemplate, 1);

    obj.onCellIndicatorClicked = function(event, col, row){
        alert("Cell indicator - " + col + " " + row);
    };

    document.write(obj);

</script>

Fantastic! This example really shows the power of the toolkit and when in the hands of someone who knows how to drive it to its full potential, it's very impressive.

Many thanks

Excellent!!

I have one minor addition.
The marker tends to sit over the ellipsis when the data overflows the cell. Our users wanted the ellipsis well to the left of the marker.
all brought about because microsoft does not implement the W3C -CSS3 spec for:
text-overflow-mode and
text-overflow-ellipsis
which would have allow a stylesheet configuration of the ellipsis. so I could add spaces at the end of it (e.g. "... ")

My setcolWidth function is where all the real work is
It may be a bit brut force and suggestions?
