• Scrolling content in a kindle book

  - by Dave

  I'm wondering if anyone is aware of a way to scroll content in a kindle book. I thought I had the problem solved by using calibre but I quickly discovered that since the content is DRMed, I'm not allowed to read the book with this reader. lame The specific book I'm reading has code examples in it, but it is difficult to follow them without being able to specifically scroll through the examples. This doesn't even touch on the fact that the code content is also poorly formatted.

• Can you use ScrollIntoView() with a PagedCollectionView in a Silverlight DataGrid?

  - by Simon

  Is it possible to scroll to a particular row (by object identity) in a Silverlight DataGrid that has an ItemsSource which is a PagedCollectionView. I am loading a list of orders that are grouped by day/status etc. I need to be able to scroll to a particular order. var pcv = new PagedCollectionView(e.Result.Orders); gridOrders.ItemsSource = pcv; Unfortunately ScrollIntoView(order) doesn't work because of the PagedCollectionView. An article on DataGrid from MSDN shows that it is possible to scroll to a group in a PagedCollectionView, but that's not really much use. foreach (CollectionViewGroup group in pcv.Groups) { dataGrid1.ScrollIntoView(group, null); dataGrid1.CollapseRowGroup(group, true); } Is there a way to do this ?

• WPF: Apply ScrollBar Style to ListBox Template - Error object cannot be added to border

  - by TheMar

  Hi, I thought this may be straightforward question but did not find any definitive answer while searching net or SO. I have created scrollbar style (using standard scroll bard template - Blend 2) I am not sure how to apply this style "MyScrollStyle" to a ListBox Template . I saw on ListBox template they have Scroll Viewer -- which should contain the scrollbar Assuming it is something simple as ---Content Added--- After going through lot of xaml in template edit I kind of understood how to apply style. I am trying to add the scroll view style set in this example -http://blog.xamltemplates.net/wp-content/uploads/2008/12/scrollviewer.zip, to my list view template but it gives error -- System.Windows.Markup.XamlParseException was unhandled Message="'ScrollViewer' object cannot be added to 'Border'. Exception has been thrown by the target of an invocation. Error at object 'System.Windows.Controls.ScrollViewer' in markup file 'MenuModule, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null;component/resources/Resources.xaml' Line 19 Position 26." Source="PresentationFramework" LineNumber=19 LinePosition=26 NameContext="1_T" Any help is appreciated Thank you, The Mar

• iChat Screen Sharing - Keyboard shortcut to switch back to my computer without messing with the mous

  - by Sergio Oliveira Jr.

  When you are watching a screen sharing session commanded by the other user, in other words, you are watching the other user doing stuff in his computer, how do I switch back to my computer without disrupting the other user by stealing the mouse to click on the "My Computer" window? Put simply: To go back to my computer I have to click in the "My computer" little window at the bottom, but that requires me to use the mouse which is being used by the other user. There must be a way to use a keyboard shortcut to perform that action without bothering the other user who is using the mouse to do something important. Anyone? Thanks, -Sergio

• jqgrid scrollable dialog

  - by gurun8

  I have a jqGrid that has add/edit dialogs with a form that's longer than the dialog height but the dialog won't scroll. I've tried to add an overflow: auto style to the dialog but no effect: $("div.ui-jqdialog-content").css("overflow", "auto"); Although, if I change auto to scroll, I at least see a scrollbar but still no scrolling: $("div.ui-jqdialog-content").css("overflow", "scroll"); This at least gives me a small glimmer of hope that I'm on the right track. There doesn't seem to be any direction from the API documentation to support scrolling: http://www.trirand.com/jqgridwiki/doku.php?id=wiki:form_editing Does anyone know how to add a working scrollbar to the jqModal dialog window used by jqGrid?

• How To AutoScroll a DataGridView during Drag and Drop

  - by Mason

  One of the forms in my C# .NET application has multiple DataGridViews that implement drag and drop to move the rows around. The drag and drop mostly works right, but I've been having a hard time getting the DataGridViews to AutoScroll - when a row is dragged near the top or bottom of the box, to scroll it in that direction. So far, I've tried implementing a version of this solution. I have a ScrollingGridView class inheriting from DataGridView that implements the described timer, and according to the debugger, the timer is firing appropriately, but the timer code: SendMessage(Handle, WM_VSCROLL, (IntPtr)scrollDirectionInt, IntPtr.Zero); doesn't do anything as far as I can tell, possibly because I have multiple DataGridViews in the form. I also tried modifying the AutoScrollOffset property, but that didn't do anything either. Investigation of the DataGridView and ScrollBar classes doesn't seem to suggest any other commands or functions that will actually make the DataGridView scroll. Can anyone help me with a function that will actually scroll the DataGridView, or some other way to solve the problem?

• YUI Menu rendering below "fold" on first open

  - by Flash84x

  I have a YUI menu on the bottom navigation of the screen which creates a large white space beneath it where the action list would be rendered if visible... On the first click the menu will render in that white space which requires the user to scroll to see it... on the second click however it will draw upward (ideally) so that the user does not have to scroll to see the menu... the second click also kills that block of white space... i found adding a style of display:none to the div kills the white space... but then YUI doesn't set the display to block, which from what I understood it should... so I wrote another method that would do that manually... but the same behavior happens, the menu first renders below the fold requiring the user to scroll.... 2nd time its works fine... some reason the top/left positions are not being calculated properly on the first click and i cannot seem to figure out why

• How to intercept UIScrollView contentOffset changes from UITableView subclass?

  - by mystify

  Actually, a UITableView is a UIScrollView (inherits from that). Now, I made a UITableView subclass and added this line of code to it: - (void)scrollViewDidScroll:(UIScrollView *)scrollView { NSLog(@"contentOffset: %@", NSStringFromCGPoint(self.contentOffset)); } For some reason this is never called when I scroll the table view. But since UITableView has a delegate property on it's own, I assume that it must implement UIScrollViewDelegate protocol and is the delegate for the scroll view itself. Isn't it? How could I intercept scroll position changes? I want to read them only. Probably I couldn't set them with contentOffset, right?

• Refreshing UIScrollView / Animation, timing (Objective-C)

  - by Switch

  I have a UIScrollView that is displaying a list of data. Right now, when the user adds one more item to the list, I can extend the content size of the UIScrollView and scroll down smoothly using setContentOffset and YES to animated. When the user removes an item from the list, I want to resize the content size of the UIScrollView, and scroll back up one step also in an animated fashion. How can I get the ordering right? Right now, if I resize the content size before scrolling back up, the scroll isn't animated. I tried scrolling back up before resizing the content size, but that still didn't give a smooth transition. Is there a way to finish the scrolling animation BEFORE resizing the content size? Thanks

• Change Ubuntu 11 scrollbars back to the old style

  - by EMP

  The question: I've installed Ubuntu 11.04 and the new scrollbars in Nautilus, GEdit, etc. are driving me insane! How do I go back to the old (Ubuntu 10.10 and earlier) scrollbars? The explanation (for those who haven't upgraded yet): In the Natty Nautilus you can't actually see a scrollbar normally. Instead you mouse over to where it should be (to the left of the border) and then it appears, but it doesn't appear under the mouse pointer! Instead it appears to the side (to the right of the border), so starting to scroll is now a fairly involved mouse manoeuvre. I don't know what UX genius came up with this, but I want none of it.

• Top/left edges of screen, in Virtualbox, act like bottom/right edges

  - by Ken

  I have Virtualbox running on Windows Vista, and Debian running inside Virtualbox. Everything's running great, for the most part. Everything looks correct. But when I'm in full-screen mode, the top edge seems to act (to the mouse) like it's the bottom edge, and the left edge seems to act like the right edge. For example, if I click in the middle of the desktop and drag left, as if to select some icons, when I hit the very leftmost pixel of the screen, the selection (but not the mouse pointer) jumps to the far right edge of the screen). For the left edge, it's not such a big deal, but not having the top edge is kind of annoying: it means I can't select things from the menu in my top panel by slamming the mouse against the top of the screen. Anyone seen this before? Is there some way to make this work? Thanks!

• Multi screens are not aligning properly

  - by Steve

  I am using (4) Samsung (SMB2230) screens. When I place my mouse on the first screen at the bottom right and pull it into the second screen the mouse jumps to the middle on the left of the second screen. Then it does the same on the 3rd and 4th screens. The biggest jump is between the 1st and 2nd then it tightens up between 2 and 3 then close between 3 and 4. This is a really pain because my mouse gets hung up and I have to move up and down to get it to change screens.I had (4) Dells screens before and this didn't happen. I'm using Windows 7

• Context Menu (Right Click) keyboard shortcut in Mac OS X

  - by czerwin

  Is it really possible to invoke a context menu using a keyboard shortcut instead of clicking the right/alt mouse button in OS X? In particular, I would like a menu-key-like feature in OS X. I am wondering whether there is an additional third party software that provides such feature. Please not that the Mouse Keys feature is not an option as I don't want to depend on the position of the mouse cursor.

• How to "restart/repair" an USB port?

  - by Click Ok

  My laptop has two USB ports, but one is broken, so I use a USB hub in the other good USB port. In that USB hub, I use a mouse and keyboard. Suddenly, that USB port doesn't detect the mouse and the keyboard (even with the light of the hub is on), and the only solution that I found is restarting the laptop. But just some minutes and the keyboard and mouse goes undetected again... Is there some method, software, etc. to "restart/repair" the USB port without restarting the PC?

• Linux Bluetooth [closed]

  - by Chris

  Not sure if this is the proper forum; please forgive me if it's not... I have a Lenovo S10 'netbook' that I've installed Fedora 17 ("LXDE spin") on. So far pretty much everything works great, except, the on-board Bluetooth. lsusb shows the controller present (0a5c:2101 Broadcom Corp. Bluetooth Controller), hcitool dev shows hci0 present, but when I put my mouse ("Lenovo Bluetooth Laser Mouse," which works perfectly paired with a MacBook Pro, MacBook Air, Mac mini, and Lenovo SL500 (with a USB dongle; running Windows 7)) into pairing mode and run either hcitool scan (reports "Scanning ..." and, without further information or error message, returns to the shell prompt) or bluetooth-wizard (from the gnome-bluetooth package) and try to detect the mouse, I get nothing... Frustrating! Thanks anyone who can point me in the right direction!

• Adding scrollbars to UserControl

  - by Bevin

  I am trying to add vertical and horizontal scrollbars to my UserControl with the HorizontalScroll and VerticalScroll properties, but I am having extreme issues. My problem arises when I drag or manipulate the scroll box on the bar. When I let it go, it simply jumps back to the start position! I know of the AutoScroll property, but I do not want to use it since I want to be able to control every aspect of my scrollbars, and I don't want it to be done automatically. Also, according to the documentation, AutoScroll is for "[enabling] the user to scroll to any controls placed outside of its visible boundaries" which isn't what I want. I just want scrollbars. ...aaand I suppose I could add VScrollBar and HScrollBar to the control, but why should I do this when the scroll functionality already exists? Seems like a waste to me.

• how do i add two delegates to a ui element at run time?

  - by Michael Xu

  Hi everyone, im trying to implement some behaviors when a mapview element scrolls... by coding a delegate for the scrollview inside of a mapview. so, right now, i got a pointer to the scroll view used by the map view in my code. however, i wish to set the delegate of this scroll view inside the map view, but the issue is that the mapview already sets up a default delegate for this scroll view inside the map view. can i make my delegate implement all of the messages of the protocol, explicitly sending them to the mapview's default delegate while also implementing my own behaviors? how else can i go about adding my own delegate behavior, to an already existing default delegate....? thanks everyone, michael

• Removing views from UIScrollView

  - by mohan

  I have two UIScrollViews that I move images between. The user can drag and forth between the scroll views. I am trying to animate the movement of the image from one scroll view to another. In -touchesMoved (handled in my UIViewController which has two custom UIScrollViews that intercept touch and sends to my UIViewController), I am trying to set the "center" of my UIImageView that is being moved. As it is moved, the image gets hidden behind the UIScrollView and not visible. How do I make it appear on top of the UIScrollView? I am able to handle the -touchesEnded properly by animating in the destination scroll view. I am also confused about -convertPoint:fromView: usage in the iPhone Programming Guide (See Chapter 3, Event Handling). If the touch coordinates are in window coordinates, to change my view (UIImageView inside a UIScrollView which is inside a UIView and inside a window) center don't I have to use -convertPoint:toView:, i.e., imageView.center = [self.view.window convertPoint:currentTouchPosition toView:imageView]; What am I missing?

• Using a KVM with a Sun Ultra 45

  - by Kit Peters

  I have a friend with two machines: a Mac and a Sun Ultra45. He wants to use a single monitor (connected via DVI) and USB keyboard / mouse with both machines. Try as I might, the Sun box will not bring up a console if the KVM is connected. However, if I connect a monitor, keyboard, and mouse directly to the Sun box, it will bring up a console that I can then (IIRC) connect to the KVM. Is there any way I can make the Sun box always bring up a console, regardless of whether it "sees" a monitor, keyboard, and mouse?

• Can USB Hubs affect peripheral performance?

  - by Daniel Rasmussen

  Like many laptops, mine has 2 USB 2.0 ports. I'm looking to purchase a USB hub for my peripheral devices. I'm also planning on purchasing a laptop cooler with two USB powered fans, which connects to a USB port but can extend the plug, so it doesn't use one up. (Sorry for the poor description; see the link for a picture.) My questions are these: Can one plug 'too many' peripherals into a USB port? Can I plug my fans into a port, then the hub into the fans, then my keyboard and mouse, mic, and webcam into the extender..? Is it possible to draw too much power from a port? Secondly, will a USB hub affect the performance of any of my devices? I'm mostly worried about my mouse and keyboard. I like wired mice because I've noticed some lag in my Bluetooth mouse.
