问题 I'm making a webpage where the user has to connect elements from two lists in a quiz. For example, imagine a quiz question where you have two lists, one with countries and one with capitals, and the user has to connect the capitals to the correct countries.

问题 I am using drag and drop in swing to place a button on one of four components. To make it more appealing instead of just the mouse indicating something being dragged (which is working fine) I wanted to show it in real time. This works except if the mouse goes back over the component being dragged the drag listener registers a dragExit event which removes the button which causes the listener to focus back on the parent component and fire a dragEnter causing a flicker. I need to make the button

问题 I am trying to implement a drag-and-drop image upload. I found a rather simple script online and adapted to my use. On my local installation the file uploads perfectly fine, but not on the server. From my debugging attempts the $_SERVER['HTTP_X_FILENAME'] does not even get set by php.

Since I have

问题 I have a custom listview, which is re-arrangeable(drag & drop) and obviously scrollable. I need to add a custom header with this listview which should scroll with the list. I have tried "listView.addHeaderView(header)" with a custom header layout. But header becomes messed up during list re-arrangement. So I don't want to use addHeaderView(...). I have also tried to put my activity layout which is a LinearLayout, inside a ScrollView and expand the list as suggested here - How can I put a

问题 I am currently working on a browsergame called "WordShuffle". (words are german at the moment for test purpose, if you want to play) My progress is going on pretty well, but I decieded to change the way how you play the game. At the moment you have to quess the word by typing your guess into a textfield. So my idea is now that people are able to rearrange the letters in a word by draging and dropping it in the right order instead of typing it into a textfield. Since I am not good at

问题 I have been looking for a drag and drop listbox, but I guess there is no such default control. A bit of searching has given me,Jason's Blog in which he has pulled it off very gracefully..
