Scroll indicator overview window - scroll

This is my first question.
I'm wondering if there's a way to create a scroll indicator with an overview image on a website. Like if I had an oversized webpage and I wanted a window in the lower right corner showing my location as I scrolled through the x and y as a cutout of the entire page.
I'm not even sure if scroll indicator is the correct term. I don't need any percentages or show of how close the scroll is to the end, I want to make an interactive display of what the user would be seeing on their screen as a piece of the overall map of the page.
Thank you for any help!

HOw to get rid of vertical "overflow:hidden" in Slick Slider

All. I am emboding the Online Store PSD design to HTML/CSS. Here is link.
There is an items slider in items page. Every item has configuration icons in the bottom of the it. When you hover on the item, second row of icons appear. Every configuration icon has its tooltip on hover. Let me describe the problem. Now because of Slick slider 'overflow:hidden' property on 'slick-list' block, the second row of icon is not visible fully. BEsides, tooltips are also being trimmed. If If I delete 'overflow:hidden', this problems disappear. But another problem appears. That is, now all slides are visible horizontally which are out of bound. If you visit the site, you notice in the bottom of the page 2 sliders. The second one has no 'overflow:hidden'. Therefore, everything is visible. But it is not good. If users monitor has high density, it looks very ugly. The first slider is by default. It has 'overflow-hidden' property , therefore everything out of bound is trimmed. I need only get rid of vertical 'overflow:hidden'. Is this possible? Thanks much, in advance.

Skrollr: Scroll down, pause, scroll to bottom

I'm sorry, but I can't get this working:
Scroll down the page to a certain position. Then pause scrolling and animate something. After that scroll down to the bottom of the page.
How do I make Skrollr scroll the end of the page without feeding absolute values to it?
I know the pausing demo, but that works with sections that always fill the whole window. But my section that follows the animated part is larger than that so I can't just say: change its position from -100% to 0% or something like that.

Highslide: Shrink image back when clicking in outer area

The only thing which I disklike whith highslide is the fact that when I click a thumbnail and it gets bigger I only can shrink it back when I click exactly in the image area.
Is it possible to shrink the image back when clicking outside the image area?
(and optional also shrink it back when I hover outside the image with the mouse cursor?)
Thanks
If you use a dimming background (hs.dimmingOpacity=0.7, for example), clicking outside the image area will close the expander. This requires highslide-full.js. If you don't want a dimming background, just set the opacity to a tiny value, like hs.dimmingOpacity=0.01.
It might be possible to include an onAfterExpand event to close the expander when you hover outside the image, but I think I can guarantee that you wouldn't like it. If a visitor clicked on a thumbnail, but didn't just happen to have his mouse over the image when it opened, it would immediately close again. That would be very frustrating behavior for the site visitor.

Drawing on an image which is inside a QScrollArea?

If I subclass QLabel and I add a QLabel directly to my QDialog, it works fine. If I add this label inside a ScrollArea, the thing I’m drawing doesn’t show unless I resize the dialog itself. Yes, weird.
I’ve setup compilable example code that indicates what the problem is. What I am trying to do is to select an area of an image with my mouse, by drawing a rectangle on the corresponding area. The images my program is designed to work with can be very large, and thus, I need to have a scroll area so as the dialog to stay at a logical dimension, and not to fill the entire screen (or even multiple workspaces, if we are talking about a linux machine with multiple desktops).
Everything works fine, except that the drawing (selection-rectangle) isn’t visible unless the dialog is resized – manually. I think I have to update something while drawing, but I’m not sure what. Well, here’s the example code: http://paste.ubuntu.com/1151553/
Another issues that I don’t know how to solve (and I want your suggestions there) are (1) when the user is selecting an area, how to set it to automatically scroll when the user actually selects an area by pushing against to a wall of the scroll area (I guess I am understandable here). (2) is there a way to let the user select a rectangle and then, when he left-clicks on a position with holding down the [Shift] button, the bottom right edge of his previous selection to actually go through the point he clicks at?
The documentation indicates that you have to set a Layout somehow somewhere, but I'm not sure how to do this to my occassion.
Thanks in advance for any help.
about problem (1):
just use of Event. i think mouse Enter Event or Leave Event is good for that.
and to do that i think you can use a hidden rectangular that fill the whole of the screen.
and over write the mouse leave Event for that rectangular and tell in that function , to scroll the page.

dojo Show/Hide One ContentPane While Another ContentPane Is Liquid

I've been struggling for weeks trying to crack this nut so I'm not sure if it's impossible, or if it's my lack of coding chops... or both. I'm not a programmer and I'm a newbie to Dojo Toolkit.
I have a site using the BorderContainer layout. I'm trying to create an effect where I can use a button to open and close a dropdown type box that will contain controls. I need this dropdown to be hidden on page load, and then open when you click the button.
My problem is that when I open the dropdown, it pushes the content pane below it off the bottom of the browser window. I need the lower ContentPane to stay fit within the remaining space of the browser window when the dropdown opens. Additionally, I want the dropdown to sit outside of the scrollable container for the content below it, which is why I have it set up to sit outside a nested BorderContainer below it.
I've created a simplified version of the code to demonstrate my challenge (see link below). If you load the page you can see the center ContentPane scrolls the content. But, if you then click on the button, a dropdown div expands above the content. Then when you scroll, you'll notice that you can't see the full pane because it's in no-man's-land below the bottom of the browser window. I assume that because the div is set to display:none on load, it's size is not accounted for on page load. Then, when you open it by pressing the button, it's size is additive and the pane below doesn't know how to resize or account for the new element.
I've tried using the visibility attribute, but that leaves a gap for the div when it's still closed. I've tinkered with some code that controls the height that shows promise, but each of my dropdown boxes will be different sizes so I'd prefer that the height be set to "auto" rather than a specified pixel size.
Does anyone have any idea how I can accomplish this so that the lower pane will fit in the space without pushing off the screen?
Here's a sample of the page:
http://equium.com/scaffold.html
(I had some problems trying to insert the full HTML page here as a code sample so if that's a preferable way to handle it, and someone can let me know the best way to embed all of that code, I'd appreciate it.)
Thanks is advance, I'd really apprecaite anyone's feedback.
You might want to take a look at dojox.layout.ExpandoPane (though be warned I think it has only worked properly for top and left regions for a while).
Also, I'd suggest simplifying/altering your layout a bit. See example here:
http://jsfiddle.net/taFzv/
(It'd probably need some tweaking to get exactly what you want.)
The real issue you're having is probably that the BorderContainer has no idea that parts of the view resized. ExpandoPane takes care of that by telling the BorderContainer to re-layout after its animation completes.
It works under IE8.0. When dropdown box open, just keep pressing mouse from page and drag to bottom, you could see the content was pushed to out of page. It looks the browser could not detect it and could not add it to "scroll bar" account.
I would suggest taking out all BorderContainers except your top level one, the one with mainPage as the id.
Place your {stuff here} div into the mainPage BorderContainer, after the ContentPane with the Close/Open button. Make sure you make it dojotype dijit.layout.ContentPane, set up layoutpriority, and set region to top. Set the height to 0/x when clicking the Open/Close button, instead of setting display.
Try your page again. If that doesn't fix it, you probably need, a call to layout, resize, or both to indicate to the BorderContainer that it needs to evaluate all its children and size the "center" pane properly. Something like dijit.byId("mainPage").layout(); Do this any time someone presses the Close/Open button, after you have changed the height of any BorderContainer children.
Maybe the dijit.form.DropDownButton would fit your needs. When click the button a tooltip is displayed that can be filled with any content you want. Just as you specified, the dropdown tooltip is only displayed when you click the button, and it doesn't mess with the underlying layout at all. The tooltip sits "on top" of the page.
