mouseover

问题 I have a set of list elements ( <li> within a <ul> ) laid out as bubbles on a chart like this, where the bubbles are the <li> elements: http://i.stack.imgur.com/PR7vR.png I want to be able to detect the difference between Moving the mouse from bubble #1 to the grid Moving the mouse from bubble #1 directly to another bubble, such as bubble 2 I've attempted to use $(this) in the .mouseleave() even for a bubble, but it registers the element that you're leaving rather than the element that you're

问题 I have subclassed NSWindow and I have a MYWindow class implementing the following method: -(void)resetCursorRects { NSImage *image = [NSImage imageNamed:@"cursor.png"]; [image setSize:NSMakeSize(32, 32)]; NSCursor *cursor = [[NSCursor alloc] initWithImage:image hotSpot:NSMakePoint(1, 1)]; [super resetCursorRects]; [self addCursorRect:[self bounds] cursor:cursor]; } This will change the cursor for the whole window and I will see cursor.png instead of the default mouse pointer. The problem is

问题 I want to put a tooltip made myself with divs when the mouse is over a marker, but I don't know how to get the screen position to put the div on the correct position, here is my code: google.maps.event.addListener(marker, "mouseover", function() { divover.css("left", marker.get("left")); divover.css("top", marker.get("top")); divover.css("display", "block"); }); google.maps.event.addListener(marker, "mouseout", function() { divover.css("display", "none"); }); Obviously the get method fails.

问题 I've looked for this everywhere for weeks, and I simply cannot find something to tell me what I'm doing wrong or how to even proceed. The goal is to create a function similar to Amazon's zoom in on mouseover for products with small images. I'm currently at a loss for how to proceed, though I am aware that I will require two images- one in the "zoomed in" size and one in the "zoomed out" size. I'm not using Jquery - I cannot install it or any plugins to the website via my employer's request. I

问题 I'd trying to style my ComboBoxes to match the rest of the UI but I'm having problems with the IsMouseOver highlighting. It highlights with the color I specify for a second and then fades back to the default color, kind of a cool effect but not what I'm going for. Here is my style: <Style TargetType="ComboBox"> <Style.Triggers> <Trigger Property="ComboBox.IsMouseOver" Value="True"> <Setter Property = "Background" Value="Red"/> </Trigger> </Style.Triggers> </Style> What can I do to make the

问题 I'm using the Draggable/Droppable functionality of Jquery to allow drag-and-drop from a TreeView to a simple HTML table, but am finding that Droppable performance gets very sluggish as the number of cells increase in the table. I've looked around and the most-common solution people suggest is limiting the number of active draggables and droppables. Now, limiting the draggables was simple enough (use the mouseover of the treeview node to enable dragging). Then I tried to do the same thing for

问题 I am trying to have an animation run only when the mouse is over an object. I can get one iteration of the animation and then have it set back to normal on mouse out. But I'd like the animation to loop on mouseover. How would I do it, using setInterval? I'm a little stuck. 回答1: It could be done like this: $.fn.loopingAnimation = function(props, dur, eas) { if (this.data('loop') == true) { this.animate( props, dur, eas, function() { if( $(this).data('loop') == true ) $(this).loopingAnimation

问题 I need some help here. I can't understand why none of the solutions I found work for my case. Let's consider a Listview with these items: <ListView.Items> <ListViewItem> <TextBlock xml:space="preserve"> 1 <Bold>I'm bold</Bold> </TextBlock> </ListViewItem> <ListViewItem> <TextBlock xml:space="preserve"> 2 Im not </TextBlock> </ListViewItem> </ListView.Items> Initially on hover each row I saw the highlight of the TextBlock in its default light blue. It only underlined the area with text: I don

问题 I want to write a paint program in the style of MS Paint. For painting things on screen when the user moves the mouse, I have to wait for mouse move events and draw on the screen whenever I receive one. Apparently, mose move events are not sent very often, so I have to interpolate the mouse movement by drawing a line between the current mouse position and the previous one. In pseudocode, this looks something like this: var positionOld = null def handleMouseMove(positionNew): if mouse.button
