Drag-and-drop from IE 9 into my application

由 半腔热情 提交于 2020-01-01 16:48:51
问题 It's kind of weird issue, let me try to explain. I wrote a (dialog based) app in c++/MFC that supports drag-n-dropping. I do the following test on Windows 7 with default themes. My app is running on the screen. It is not a top window (in its z-order) or in other words it's obscured by other windows on top of it. If I begin dragging a link or just a text selection from the Chrome or Firefox web browser, first into my app's icon on the taskbar, the icon flashes and my app pops up on the screen

Javascript file dropping and reading directories - Asynchronous Recursion

由 允我心安 提交于 2020-01-01 15:38:07
问题 So I'm trying to create a file dropper web application. Right now, a user can drop files on the screen and I can read them, including all the files in a directory that was dropped. But, I don't know when the script is done reading the files. Some code: This first function handles a 'drop' event and will loop through each file and send it to another function that will read its contents. function readDrop( evt ) { for( var i = 0; i < evt.dataTransfer.files.length; i++) { var entry = evt

问题 QT5.5, QML: I am using the example "Qt Quick Examples - Drag and Drop" In this example, you could see that if we drag the red tile "1", it appears under other tiles when we drag it. I don't like this effect since when we drag one item, I hope it always appears on the top of whole GUI. What I tried is: Once the mouse is pressed, we set the item's z as the largest value. And when the mouse is released, set the z to the small value (or better we could save the original value and reset it back to

Prevent drag drop of custom mimetype to EditText

由 空扰寡人 提交于 2020-01-01 08:36:09
问题 I have a custom mime type which I am intending to use to drag and drop application objects within the app. This seems to be working but I'm finding that the EditText fields are also accepting the drop action. I don't want this to happen. First, I've defined the custome mime type like this: public static final String MIME_TYPE_MYNODE = "com.example.mockup/mynode"; Then, in the onTouch handler for the source object I have: @Override //------------------------------------------------------------
