mouseevent

I am a quite new user of matplotlib. When plotting a surface (3D) with matplotlib and plot_surface, a window appears with the graph. In that windows, on the bottom right corner there is the coordinates of the actual position of the mouse. Is is possible to gain access to these values ? I have search on internet but very few solutions are proposed. For a 2D plot, these values are accessible using a tkinter.canvas but in 3D, when using the same technique the event.xdata and event.ydata did not return the good position for the mouse. Thank you in advance for your precious help, Antoine Thilo With

I have been writing a test function to learn how a mouse 'click' action on a pygame.rect will result in a reponse. So far: def test(): pygame.init() screen = pygame.display.set_mode((770,430)) pygame.mouse.set_visible(1) background = pygame.Surface(screen.get_size()) background = background.convert() background.fill((250,250,250)) screen.blit(background, (0,0)) pygame.display.flip() ## set-up screen in these lines above ## button = pygame.image.load('Pictures/cards/stand.png').convert_alpha() screen.blit(button,(300,200)) pygame.display.flip() ## does button need to be 'pygame.sprite.Sprite

Let's say I have a widget in main window, and want to track mouse position ONLY on the widget: it means that left-low corner of widget must be local (0, 0). Q: How can I do this? p.s. NON of functions below do that. widget->mapFromGlobal(QCursor::pos()).x(); QCursor::pos()).x(); event->x(); I am afraid, you won't be happy with your requirement 'lower left must be (0,0). In Qt coordinate systems (0,0) is upper left. If you can accept that. The following code... setMouseTracking(true); // E.g. set in your constructor of your widget. // Implement in your widget void MainWindow::mouseMoveEvent

If you take a look at Visual Studio 2012, you'll notice that if you use the mouse wheel, the window under your mouse will scroll, and not the focused window. That is, if you have your cursor in the code editor, and move your mouse over the Solution Explorer window and scroll, the Solution Explorer will scroll, and not the code editor. The WM_MOUSEWHEEL message, though, only gets sent to the focused window, so in this case, the code editor. How can we implement our program such that the WM_MOUSEWHEEL messages scroll the window under the mouse, which is intuitive, and not the focused window?

If a mouse has other buttons in addition to the standard left/right/middle (e.g. forward/back), how can we detect those button clicks in Delphi? An example of how this is used is the Internet Explorer, where the forward/back button on the side of a Logitech or MS mouse cycles forward and back between any loaded web pages. This seems to replicate the Backspace/CTRL+Backspace on the keyboard but I tried to detect that using KeyPreview and the KeyPress event but it does not pick it up. Any idea how to detect clicks on these extended mouse buttons? Zoë Peterson You need to capture the WM

I have a function in javascript that moves one div depending on the mouse position. This function is set on a setInterval() function and executed every second. I need to capture the mouse position like this: function mousemov() { document.getElementById("myDiv").style.left = Event.clientX; //don't work } window.onload = function() { setInterval("mousemov()",1000); } Ps: I cannot use the mousemove event because the function must be executed even if the mouse is stopped. Thanks for helps! The only time that you can access the event object is during the execution of an event handler. So what you
