Just use back_mc.clear() in your resize() method just before drawing it
again. But, why don't you just draw it once outside of the resize method
and then resize it with the _width and _height properties???

Hello!
I'd like to draw a green rectangle underneath 2 TextFields.
As my flash app. will have WIDTH=100% in the HTML-page,
I'd like to handle the eventual resizing of it. For that I've registered
an onResize-listener at the Stage (see the resize() function below).
While resizing works ok for the both TextFields (called area_txt
and field_txt), it fails for the green rectangle: the old rectangle
doesn't get erased. Does anybody please have an advice for me?
I don't see any Stage.clear() method in the help-docs...
I've prepared a complete test case below, please copy-paste it
and resize the movie window and you'll see the problem I have:
createEmptyMovieClip('back_mc', getNextHighestDepth());
createTextField('area_txt', getNextHighestDepth(), 5, 5, 5, 5);
with (area_txt) {
border = true;
multiline = true;
textColor = 0xFFFFFF;
}
createTextField('field_txt', getNextHighestDepth(), 5, 5, 5, 5);
with (field_txt) {
border = true;
type = 'input';
textColor = 0xFFFFFF;
}
resize();
Stage.scaleMode = 'noScale';
var resizeListener:Object = new Object();
resizeListener.onResize = resize;
Stage.addListener(resizeListener);
function resize() {
trace("Stage size: " + Stage.width + " x " + Stage.height);
var text_width:Number = 3 * Stage.width / 4;
var text_left:Number = 10;
// draw a rectangle with a cut-off corner
with (back_mc) {
_alpha = 50;
moveTo(text_left + 8, 30);
lineStyle(0, 0xFFFFFF, 100);
beginFill(0x008000, 100);
lineTo(text_left + text_width, 30);
lineTo(text_left + text_width, 290);
lineTo(text_left, 290);
lineTo(text_left, 30 + 8);
endFill();
}
with (area_txt) {
_x = text_left;
_y = 30;
_width = text_width;
_height = 240;
}
with (field_txt) {
_x = text_left;
_y = 270;
_width = text_width;
_height = 20;
}
}
Also I wonder, if there is a way to encapsulate the rectangle
drawing code insided the back_mc MovieClip? Then I'd just
have to position it and to change its _width and _height and
wouldn't need to touch its drawing guts (i.e. OOP-encapsulation).
I've tried create a MovieClip symbol and to put this code
into its 1st frame, but that didn't work (nothing was drawn):
_alpha = 50;
moveTo(8, 0);
lineStyle(0, 0xFFFFFF, 100);
beginFill(0x008000, 100);
lineTo(_width, 0);
lineTo(_width, _height);
lineTo(0, _height);
lineTo(0, 8);
endFill();
Thank you
Alex
