mousewheel

I'm having a problem getting mouse wheel scrolling to work in the following XAML, which I have simplified for clarity: <ScrollViewer HorizontalScrollBarVisibility="Visible" VerticalScrollBarVisibility="Visible" CanContentScroll="False" > <Grid MouseDown="Editor_MouseDown" MouseUp="Editor_MouseUp" MouseMove="Editor_MouseMove" Focusable="False" > <Grid.Resources> <DataTemplate DataType="{x:Type local:DataFieldModel}" > <Grid Margin="0,2,2,2" > <TextBox Cursor="IBeam" MouseDown="TextBox_MouseDown" MouseUp="TextBox_MouseUp" MouseMove="TextBox_MouseMove" /> </Grid> </DataTemplate> </Grid.Resources>

I'm using Jquery mousewheel plugin and I would like like to be able to detect when the user has finished using the wheel. Similar functionality as the stop: event in the draggable stuff. Can somebody point me to the right direction? There's no "stop" event here really - you get an event when you do scroll, so every time a mousewheel event happens the event is triggered...when there's nothing you'll get no events and your handler won't be firing. You ca however detect when the user hasn't used it in say 250ms, like this: $("#myElem").mousewheel(function() { clearTimeout($.data(this, 'timer'));

I have created a delphi component which descends from TGraphicControl. Is it possible to add support for mouse wheels? --- Edit --- I've exposed the MouseWheel events as shown below but they aren't called. TMyComponent = class(TGraphicControl) published property OnMouseWheel; property OnMouseWheelDown; property OnMouseWheelUp; end; --- Edit --- As suggested below, I've tried to trap the WM_MOUSEWHEEL and CM_MOUSEWHEEL messages, but it doesn't seem to work. However I've managed to trap the CM_MOUSEENTER message. I don't understand why i can trap one type of message, but not the other. NGLN Due

I'd like to have clean and nice JavaScript for mousewheel event, supporting only the latest version of common browsers without legacy code for obsolete versions, without any JS framework. Mousewheel event is nicely explained here . How to simplify it for the current latest versions of the browsers? I don't have access to all browsers to test it, so caniuse.com is a great help to me. Alas, mousewheel is not mentioned there. Based on Derek's comment, I wrote this solution. Is it valid for all browsers? someObject.addEventListener("onwheel" in document ? "wheel" : "mousewheel", function(e) { e

I have this scroll-able frame (frame inside canvas actually). import Tkinter as tk class Scrollbarframe(): def __init__(self, parent,xsize,ysize,xcod,ycod): def ScrollAll(event): canvas1.configure(scrollregion=canvas1.bbox("all"),width=xsize,height=ysize,bg='white') self.parent=parent self.frame1=tk.Frame(parent,bg='white') self.frame1.place(x=xcod,y=ycod) canvas1=tk.Canvas(self.frame1) self.frame2=tk.Frame(canvas1,bg='white',relief='groove',bd=1,width=1230,height=430) scrollbar1=tk.Scrollbar(self.frame1,orient="vertical",command=canvas1.yview) canvas1.configure(yscrollcommand=scrollbar1.set)

UPDATE: Here is a jsbin example demonstrating the problem. UPDATE 2: And here is the fixed version thanks to fudgey . Basically, I have the following javascript which scrolls the window to an anchor on the page: // get anchors with href's that start with "#" $("a[href^=#]").live("click", function(){ var target = $($(this).attr("href")); // if the target exists: scroll to it... if(target[0]){ // If the page isn't long enough to scroll to the target's position // we want to scroll as much as we can. This part prevents a sudden // stop when window.scrollTop reaches its maximum. var y = Math.min
