I'm pretty new to Openlayers and I have a problem with map panning using middle mouse button. Basically, I want to use the middle mouse button only for map panning, so that when other tools are selected/used (as identify feature tool) the middle mouse won't be used for selecting (only left mouse button).
Any suggestion?

I want to make a query function for 3d tile. When i search a tile, the tile's contour will highlight (like 3D Tiles Feature Picking Demo). In Cesium demo, they pick a tile feature by mouse click event, but i don't want to pick a tile feature by mouse click. I want to give pick function a value (for example: viewer.scene.pick(Cesium.Cartesian2(309,306));), then i can get that tile.
In Cesium, how can I auto trigger click event without mouse click when I want to pick a 3d tile feature ? If no, how should I do?
I have a Leaflet map and I want to completely disable panning whether using the mouse, touchscreen, or keyboard, so that the map appears like a static image. I have added map.dragging.disable(); which works for mouse dragging.
But when the map container is focused using the Tab key, pressing the arrow keys on the keyboard will still pan the map. Is there any solution for this?
I think that there are a couple options on Leaflet maps that should resolve your issue.
First, the dragging option, if false, should prevent the mouse from dragging the map.
Next, the keyboard option, if false, should prevent the user from navigating the map with the keyboard.
Also, you should consider setting doubleClickZoom to false if you want your map to be static.
Finally, examine the map option documentation to ensure that I haven't missed any relevant options.
Hope this helps.
I'm using D3's zoom behavior on a large world map.
var zoom = d3.behavior.zoom().scaleExtent([1, 100]);
It works great, providing a natural zoom functionality and disabling the usual scroll activity one expects from a MouseWheel event, as it should.
However, when the map takes up the whole screen, I worry that users will get frustrated if they try to scroll down using the mouse wheel when the map is zoomed all the way out. Is there a way to bubble up to this behavior only in that circumstance?
A good example is the way a scrollable DIV on the page will scroll down when the mouse wheel is used over top of it. But when it reaches the bottom, the page itself resumes scrolling down.
I don't know a lot about event bubbling, but I do see that the D3 zoom behavior does called a d3.event.preventDefault().
I am trying to use
d3.js Multiple Area Chart for representing a collection of data. The graph building part was completed successfully. I've created a brush for timeline dragging and the bug is that, I guess, the mousedown event is not recognised by the brush. When I click on the context area (brush), I don't have to drag and release the mouse to select an area. After clicking the selection of area goes to left and right automatically depending on the direction my mouse moves. Is that some kind of bug or due to some changes that I made in the code?
I am using jqZoom Evolution to implement zoom functionality on my site, the problem is that it does not have the functionality for the zoom box to follow my mouse pointer around as I hover over a image, I have tried using mousemove to make it follow the cursor around, but every time I resize the browser the box moves further away from the cursor,
$("#single_main_container").mousemove(function(e){
$(".zoomWindow").css({
top: e.pageY,
left: e.pageX
});
});
so basically I just need the zoom box to follow my mouse cursor around when I hover over the image.
its not following your cursor?
but the 1st demo is showing zoom as you move your mouse

Edit
not exactly a solution but an alternative plugin which provides mouseover zoom out-of-box
