I am trying to add a scrollbar to one of my panels (something I have tried for many years unsuccessfully).
I stumbled across Peter Kahrel's ScriptUI documentation and he has the following working code
var w = new Window('dialog');
w.maximumSize.height = 300;
var panel = w.add ('panel {alignChildren: "left"}');
var scrollGroup = panel.add ('group {orientation: "column"}');
for (var i = 0; i <= 35; i++) {
scrollGroup.add ('statictext', undefined, 'Label ' + i);
}
var scrollBar = panel.add ('scrollbar {stepdelta: 20}');
// Move the whole scroll group up or down
scrollBar.onChanging = function () {
scrollGroup.location.y = -1 * this.value;
}
w.onShow = function() {
// Set various sizes and locations when the window is drawn
panel.size.height = w.size.height-20;
scrollBar.size.height = w.size.height-40;
scrollBar.size.width = 20;
scrollBar.location = [panel.size.width-30, 8];
scrollBar.maxvalue = scrollGroup.size.height - panel.size.height + 15;
};
w.show();
my problem is, if I add more rows by changing line 05 to this
for (var i = 0; i <= 300; i++) {
when I scroll the panel it gets to around 35 elements and then there is just blank area in the panel beyond that row.
Anybody good with this stuff, it is something I have needed to do for a long time but adobe's documentation really sucks.
