drag-and-drop

问题 I have a range of drag drop activities all working fine on my quiz. (From answering questions to selecting an avatar) There is a lot of repetition of the code and I am thinking it would be better implemented from a class and call the method each time that I use a drag drop. Firstly can this be done? and secondly would I need a new method for the dragging and dropping? Any thoughts or rough ideas would be great. private void pictureBox2_MouseDown(object sender, MouseEventArgs e) { pictureBox2

问题 I have a app which has a large grid with a stack-panel and stack-viewer. Inside there are multiply grids which go down the page. Is it possible for the user to be able to drag and drop these grids so they are in a different location. They should be able to move the grid up or down a grid or multiply grids. Should there be a button in the top right corner of every grid which when the user holds down they can move that grid up or down in the stackpanel, stackviewer. Thank you for any help :)

问题 In all major Java IDEs, there is a GUI designer. When we select a component (A Jbutton , for example) and move it to a JPanel or JFrame , how is it done? Is it a copy of the dragged component that is created on the other container? On a project I'm working on, I have some JButton I would like to be able to drag to a panel. Theses JButton represent some actions, like "copy file", "move file", etc... When one of those JButton is dragged, some options of the action will be displayed. I checked

问题 I am new to DOJO and trying to figure out the difference between these two uses of the seemingly two things. dndController: new dijit.tree.dndSource("dijit.tree.dndSource",{copyOnly:true}) and dndController: "dijit.tree.dndSource" The second one works, but when I use the first one, it gives me an error when loading my tree. It says type node is undefined. The reason I want to use the first one though is because I want to set copyOnly to true. Any answers appreciated it. 回答1: That parameter

问题 I am trying to 'swap' two cells' contents, and their mappings. To do this, I need to drag and drop a reference to the cell as opposed to the string value itself. I can then use this reference to update a Dictionary as well as get the value. It allows allows me to do the swap as I will have a reference to the old cell to add the value needed in there.
