Hi!
I have an data grid with two columns renderee as input text. all works
fine (i read some on the net), but i have two problems:
1. data grid display input text in rows, even if i don't have any
value for that row (is ugly).
2. after i input some text in and delete that row (due to my script),
value remain in next input cell. I resolve that, some how, re-renderer
columns after data is reloaded, but i don't like that solution.
This is my class for renderer column in datagrid
import mx.core.UIComponent;
import mx.controls.TextInput;
import mx.controls.DataGrid;
class TextInputCellRenderer extends UIComponent {
var input:MovieClip;
var listOwner:DataGrid;
// the reference we receive to the list
var getCellIndex:Function;
// the function we receive from the list
var getDataLabel:Function;
// the function we receive from the list
var width_input:Number;
function TextInputCellRenderer() {
}
function createChildren(Void):Void {
//This is where you can set the properties of the TextInputs
for this column
//For instance, you can set the maxChars and the restrict
properties
//And adds an eventListener for 'change' (which is defined at
the bottom of this code),
//so that whenever you type anything in the TextInput, it
writes it to the dataGrid
input = createObject("TextInput", "TextInput", 1,
{styleName:this, owner:this});
input.maxChars = 15;
input.restrict = "0-9 a-z";
input.text = "";
input.addEventListener("change", this);
size();
}
// note that setSize is implemented by UIComponent and calls size(),
after setting
// __width and __height
function size(Void):Void {
input.setSize(__width-20, 18);
//---set this to whatever the width of the column, and the
height of the dataGrid rows.
input.setStyle("fontSize", 11);
input._x = 8;
input._y = 1;
}
/*
function setValue(str:String, item:Object, sel:Boolean) : Void
{
//Displays the dataGrid's cell value in the TextInput
//input._visible = (item!=undefined);
input._visible = true;
input.text = str;
}
*/
function change() {
//----the 'change' function, which writes the textInput's input
text into the dataGrid field that the TextInputCellRenderer is sitting in.
listOwner.dataProvider.editField(getCellIndex().itemIndex,
getDataLabel(), input.text);
}
}
