Mythoughts 1 4. In HTML, any element can be dragged and dropped.
Example
The magnitude of the drag generated by an object depends on the shape of the object and how it moves through the air. For thin airfoils, the drag is nearly constant at small angles (+/- 5 degrees). As the angle increases above 5 degrees, the drag quickly rises because of increased frontal area and increased boundary layer thickness. My goal is to have a QTableWidget in which the user can drag/drop rows internally. That is, the user can drag and drop one entire row, moving it up or down in the table to a different location in between two other rows.

Drag and Drop
Drag and drop is a very common feature. It is when you 'grab' an object and drag it to a different location.
Browser Support
The numbers in the table specify the first browser version that fully supports Drag and Drop.

HTML Drag and Drop Example
The example below is a simple drag and drop example:
Example
<!DOCTYPE HTML>
<html>
<head>
<script>
function allowDrop(ev) {
ev.preventDefault();
}
function drag(ev) {
ev.dataTransfer.setData('text', ev.target.id);
}
function drop(ev) {
ev.preventDefault();
var data = ev.dataTransfer.getData('text');
ev.target.appendChild(document.getElementById(data));
}
</script>
</head>
<body>
<div ondrop='drop(event)' ondragover='allowDrop(event)'></div>
<img src='img_logo.gif' width='336' height='69'>
</body>
</html>
Try it Yourself »<html>
<head>
<script>
function allowDrop(ev) {
ev.preventDefault();
}
function drag(ev) {
ev.dataTransfer.setData('text', ev.target.id);
}
function drop(ev) {
ev.preventDefault();
var data = ev.dataTransfer.getData('text');
ev.target.appendChild(document.getElementById(data));
}
</script>
</head>
<body>
<div ondrop='drop(event)' ondragover='allowDrop(event)'></div>
<img src='img_logo.gif' width='336' height='69'>
</body>
</html>
It might seem complicated, but lets go through all the different parts of a drag and drop event.
Make an Element Draggable
First of all: To make an element draggable, set the
draggable
attribute to true:What to Drag - ondragstart and setData()
Space Drop: Better Drag & Drop 1 7 44
Then, specify what should happen when the element is dragged.
In the example above, the
ondragstart
attribute calls a function, drag(event), that specifies what data to be dragged.The
dataTransfer.setData()
method sets the data type and the value of the dragged data: function drag(ev) {
ev.dataTransfer.setData('text', ev.target.id);
}
ev.dataTransfer.setData('text', ev.target.id);
}
In this case, the data type is 'text' and the value is the id of the draggable element ('drag1').
Where to Drop - ondragover
The
ondragover
event specifies where the dragged data can be dropped.By default, data/elements cannot be dropped in other elements. To allow a drop, we must prevent the default handling of the element.
This is done by calling the
event.preventDefault()
method for the ondragover event:Do the Drop - ondrop
When the dragged data is dropped, a drop event occurs.
In the example above, the ondrop attribute calls a function, drop(event):
function drop(ev) {
ev.preventDefault();
var data = ev.dataTransfer.getData('text');
ev.target.appendChild(document.getElementById(data));
}
ev.preventDefault();
var data = ev.dataTransfer.getData('text');
ev.target.appendChild(document.getElementById(data));
}
Code explained:
- Call preventDefault() to prevent the browser default handling of the data (default is open as link on drop)
- Get the dragged data with the dataTransfer.getData() method. This method will return any data that was set to the same type in the setData() method
- The dragged data is the id of the dragged element ('drag1')
- Append the dragged element into the drop element

thanks in advance.
thanks in advance.
I dont think there are any although it may depend on the video player you are using.
Not sure if I understand you completely, but if you could just have the subtitle files alongside the video files (both must have same file names), players like VLC Media Player should automatically detect and display it with the video. Is that the desired result?
Yeah sure you don't understand me.hehe. What i mean is that keyboard shortcut key for draging and droping a file.
Example, for right click using keyboard shortcut is shift+F10.

The only way that I know of is by copy (ctrl+C) and paste (ctrl+P), you can't really 'drag' with a keyboard. You can use Alt+Tab to cycle through open windows.
I think you can drag and drop a file with the keyboard by using the accessibility wizard
Accesories then ease of access in Vista
in XP and earlier win systems I think it is -accessories -then accesibility-then accessibility wizard
just go through it an say you have trouble using a mouse and one of the options about using the keyboard will let you drag and drop with the keyboard.

I always set mine up so I can move the mouse with the number pad in case the mouse don't work. I just set the speeds as fast as they can go and it very helpful to me as I have trouble using a mouse sometimes because of my tremors in my hands.
Hope this helps.

There is a way in Windows 7 (Im not sure about Vista or XP ect.) by using control the mouse using a keyboard.
To turn on mouse keys in windows 7:
1) Navigate to 'ease of access centre' (Control Panel >Ease of Access > Ease of Access Centre)
2) Click Make the mouse easier to use.
3) Under Control the mouse with the keyboard, select the “Turn on Mouse Keys” check box.
4) Then 'set up mouse keys' to your desired preferences.

Using this you should be able to emulate dragging.
