I've created a ListBox to display items in groups, where the groups are wrapped right to left when they can no longer fit within the height of the ListBox's panel. So, the groups would appear similar to this in the listbox, where each group's height is arbitrary (group 1, for instance, is twice as tall as group 2): [ 1 ][ 3 ][ 5 ] [ ]...
Anyone could point me to some code/give me ideas on how to create a smooth scrolling vertical marquee for VFP 8,9 Any help is appreciated. Nelson Marmol ...
I have a little logging app (written in wxPython) that receives data from a bit of kit we're developing, and I want to display the text in a scrolling window. As it stands I'm using a wx.TextCtrl for the text display, but I'm having some issues with the scrolling behaviour. Basically, I'd like it so that if the scrollbar is at the botto...
In an app I'm working on, I have a plain style UITableView that can contain a section containing zero rows. I want to be able to scroll to this section using scrollToRowAtIndexPath:atScrollPosition:animated: but I get an error when I try to scroll to this section due to the lack of child rows. Apple's calendar application is able to do ...
WPF, Browserlike app. I got one page containing a ListView. After calling a PageFunction I add a line to the ListView, and want to scroll the new line into view: ListViewItem item = ItemContainerGenerator.ContainerFromIndex(index) as ListViewItem; if (item != null) ScrollIntoView(item); This works. As long as the new line is i...
Hello! I am working on a 2D scrolling game for iPhone. I have a large image background, say 480×6000 pixels, of only a part is visible (exactly one screen’s worth, 480×320 pixels). What is the best way to get such a background on the screen? Currently I have the background split into several textures (to get around the maximum texture s...
I am building a utility page for a web app that I am working on. I have an element that I want to use as a "console" of sorts. I get entries for the console via Ajax calls (using prototype's Ajax.PeriodicalUpdater). The problem I'm having is that when I insert new lines to the bottom of the "console", the scrollbar stays in the initi...
I am trying to synchronize the horizontal scroll position of 2 WPF DataGrid controls. I am subscribing to the ScrollChanged event of the first DataGrid: <toolkit:DataGrid x:Name="SourceGrid" ScrollViewer.ScrollChanged="SourceGrid_ScrollChanged"> I have a second DataGrid: <toolkit:DataGrid x:Name="TargetGrid"> In the event handler ...
How can I create a table that has its first row and first column both locked, as in Excel, when you activate 'freeze panes'? I need the table to both scroll horizontally and vertically (a lot of solutions for this exist, but only allow vertical scrolling). So, when you scroll down in the table, the first row will stay put, since it wil...
We have a UI widget on our main UI that uses JavaScript to respond to scrolling events from the browser. The response to each scroll event is relatively expensive. A user can easily "queue" up a large set of scrolling events, while the first several are being processed and rendering within the widget. The problem with this is that then ...
I have a single line CEikLabel in my application that needs to scroll text. The simple solution that comes to mind (but possibly naive) would be something like.. [begin pseduo code] on timer.fire { set slightly shifted text in label redraw label } start timer [end pseudo code] Using a CPeriodic class as the timer and label.D...
I'm working on a canvas app embedded in a page. I have it so you can zoom into the drawing with the mousewheel but unfortunately this scrolls the page as it is part of an article. Is it possible to prevent mousewheel scrolling on the window when I'm mousewheeling on a dom element?! ...
Hello, When using Google Reader and browsing RSS entries in the "Expanded" view, entries will automatically be marked as 'read' once a certain percentage of the div is visible on the screen (difficult to tell what percentage has to be visible in the case of Google Reader). So, as I scroll down line-by-line, the javascript code can deter...
Hopefully, this will be an easy answer for someone with Javascript time behind them... I have a log file that is being watched by a script that feeds new lines in the log out to any connected browsers. A couple people have commented that what they want to see is more of a 'tail -f' behavior - the latest lines will always be at the bott...
Basically what I want to do is allow a user to type in a string value and have the list box scroll to the item that matches the text they have typed (or the first LIKE match). If I use the .ScrollIntoView() method, the problem is that it puts the item at teh bottom of the visible area if the item is further down in the list than the cur...
Hello, In an HTML page, if I align some <div>s with "right: 0px", they all look very nice, as I expect. However, if I make the browser window smaller and the horizontal scroll bar appears, when I scroll the page to the right, I see an unexpected white space (instead of the background colors of my <div>s). It seems that my <div>s are ali...
How do I initialize a GtkScrolledWindow to avoid scrollbars by growing as much as possible? By default it seems to be as small as possible. Demo code (Quit with SIGINT): #include <gtk/gtk.h> int main(int argc, char *argv[]) { GtkWidget* window; GtkWidget* content; GtkWidget* sw; gtk_init(&argc, &argv); window = g...
When I scroll in Emacs using mouse wheel, it scrolls 5 lines at a time, which, I think, is way too much - where do I set a new value? Also, when I scroll in Emacs with a mouse (either wheel or scrollbar), the cursor jumps to stay inside the visible screen area - is there a way to override that behavior, making it staying on the line it ...
I have a Graph being drawn inside a UIScrollView. It's one large UIView using a custom subclass of CATiledLayer as its layer. When I zoom in and out of the UIScrollView, I want the graph to resize dynamically like it does when I return the graph from viewForZoomingInScrollView. However, the Graph redraws itself at the new zoom level, ...
I'm looking to create a (possibly 3D) scrolling credits screen for my app, that is similar to what you might see at the end of a movie, but should be able to include graphics, animations, etc. What is the best way to go about doing this? I'm thinking I could create a very tall UserControl that contains the entire content to scroll and t...
