问题 I know this title sounds a lot like Detect mouseover an image in Pygame but there's an error. I've tried following both answers from that question, but it never worked. Here is a part of my code: title = font3.render(('SQUASH!'), True, white) play = font1.render(('PLAY'), True, white) while True: for event in pygame.event.get(): if event.type == QUIT: pygame.quit() sys.exit() screen.blit((title), (400, 400)) screen.blit(play, (theposition)) if play.collide_point(pygame.mouse.get_pos()): hi =

问题 I have referred to a lot of tutorials on how to control your mouse cursor's movements and clicks by map these events to your own real mouse, but I noticed that everytime I must associate this mouse to one specified event in /dev/input/, if I didn't connect one real mouse, or if the linux didn't give the right event number on this real mouse, the program will definitely fail. Now I need to write a generalized program which can make one complete virtual mouse on linux, that is to say, this

问题 In my java application, i m trying to change the mouse cursor with an argb 32bit bmp file with transparency. I want to make a jni call to change it from Windows because changing the cursor in java gives me a really bad mouse cursor (all the transparency is either 0x00 or 0xFF) At the moment i'm trying to use the function SetClassLong with as parameters: the hWnd from java (i got it following that method http://download.oracle.com/javase/1.3/docs/guide/awt/AWT_Native_Interface.html ) GCL

问题 I've got a problem when trying to drag a JPanel. If I implement it purely in MouseDragged as: public void mouseDragged(MouseEvent me) { me.getSource().setLocation(me.getX(), me.getY()); } I get a weird effect of the moved object bouncing between two positions all the time (generating more "dragged" events). If I do it in the way described in this post, but with: public void mouseDragged(MouseEvent me) { if (draggedElement == null) return; me.translatePoint(this.draggedXAdjust, this

问题 Cursor.Position, SetCursorPos(), SendInput() and mouse_event() all set the mouse position to a specified coordinate. So what's the difference between them? 回答1: Cursor.Position and SetCursorPos can only be used to change the cursor position. Cursor.Position is Windows Forms; SetCursorPos is Win32. SendInput and mouse_event can be used to change the cursor position as well as generate mouse clicks and mouse wheel events. SendInput is the current API; in addition to generating mouse events, it

问题 How do I execute a function when a user's mouse hovers over my NSStatusItem? 回答1: If you assign a custom NSView to your NSStatusItem 's view property, you can override the NSResponder methods mouseEntered: , mouseMoved: and mouseExited: . 来源： https://stackoverflow.com/questions/5114974/cocoa-capturing-nsstatusitem-mouse-hover-event

问题 The issue of programmatically drawing lines using XNA has been covered here. However, I want to allow a user to draw on a canvas as one would with a drawing app such as MS Paint. This of course requires each x and/or y coordinate change in the mouse pointer position to result in another "dot" of the line being drawn on the canvas in the crayon color in real time. In the mouse move event, what XNA API considerations come into play in order to draw the line point by point? Literally, of course,

问题 I know how to 'drag and move' a winform by adding following code Protected Overrides Sub WndProc(ByRef m As Message) If (((m.Msg = 163) And ClientRectangle.Contains(PointToClient(New Point(m.LParam.ToInt32)))) And (m.WParam.ToInt32 = 2)) Then m.WParam = CType(1, IntPtr) End If MyBase.WndProc(m) If ((m.Msg = 132) And (m.Result.ToInt32 = 1)) Then m.Result = CType(2, IntPtr) End If End Sub But after a panel being added to winform, I can not 'drag and move' the winform within that panel area.

问题 I'm having a real issue trying to define a function for where I click on empty space. So far I have managed to define where I click on an object - of which there are 10 - but now I need a separate function for when I am not clicking on any of the objects. The general idea can be found at http://deciballs.co.uk/experience.html. The objects are the rings. My code is below... Any ideas? var shapeObj = function (context, canvas, settingsBox, radius) { this.ctx = context; this.canvas = canvas;
