messagetrying to drag an image in the horizontal pane
Hello, my first post.

I have a new widget and I want to click on a visual element (a hand-made slider) and then slide it only in the horizontal plane within two boundaries.

I have used onMouseDown and system.event.hOffset to move it and that has been successful to a certain extent. However, it only moves the slider at the point at which the mouse button is depressed. It won't keep on dragging. I want to be able to keep dragging the slider according to the current mouse position with the mouse button pressed - a normal drag. I have found the yahoo documentation obscure and confusing and I'm looking ofr help only after a lot of digging.

I am using the current version of Yahoo widgets. I have no sample code as I just deleted the whole function after giving up... the XML is simply:

<onMultiClick> <![CDATA[
<onMouseDown> <![CDATA[
// ]]> </onMouseDown>

I believe the code to do this very simple I am just completely unacquainted with Javascript syntax and really need your help!

FYI - an image of the widget is here in an earlier form, at least you can see the slider

An early version of the widget can be seen here:
feel free to try a download - it does not do much

Hey, welcome!

I didn't look too careful, but at the first glance I'd say that you need to execute the slidermove() function also on the onMouseMove event, not just on the drag - e.g. something like this:

<onMouseDown> <![CDATA[
dragEnabled = 1;
// ]]> </onMouseDown>

<onMouseMove> <![CDATA[
if (dragEnabled) {slidermove(); }
// ]]> </onMouseMove>

<onMouseUp> <![CDATA[
dragEnabled = 0;
// ]]> </onMouseUp>

Hope that helps! thumbs down

Adrian, you are a good man! Firstly for replying so quickly and secondly for giving me the exact fix I required. I am implementing it now. Give me a while and I might even be an expert myself - one day perhaps! What did you think of the SteamPunk widget?

Working with Effect Presets in Adobe Premiere Elements

To make using and modifying video effects easier, Premiere Elements comes with a collection of effect presets. Each preset is a collection of settings that perform common tasks like panning across a still image or creating a picture-in-picture (PiP) effect. Rather than spending minutes or even hours fine-tuning motion controls, keyframes, and other effect settings, you just drop a preset onto the clip, thereby applying a raft of predetermined settings instantly. These presets are incredible timesaving tools even veteran video professionals could appreciate.

Using a preset is easy. Simply drag and drop a preset from the Effects window to a video clip, just as you would with any other effect. All settings related to the preset are applied to the clip; however, you can always fine-tune the settings if you wish.
