tkinter - Widget does not detect entry of mouse when the mouse is held down before entering widget

由 淺唱寂寞╮ 提交于 2019-12-08 05:30:04
问题 How can I trigger an event that fires when the mouse enters a widget (e.g. a Frame) while the mouse is held down? It seems that the event in question only fires when the mouse is up. I'm using this code (approximately) so far: self._root_window = tkinter.Tk() self._root_frame = tkinter.Frame() self._root_frame.pack(fill=tkinter.X, padx=5, pady=5) frame = tkinter.Frame(master=self._root_frame, ...) self._root_window.bind('<Button-1>', self._on_button_down) self._root_window.bind('

问题 I'm working on a canvas javascript where with the mousemove event you can erase the background... Now i'm trying to get the same experience for touchscreens (mobile).

How to create a reusable toggle button in AS3?

由 北城余情 提交于 2019-12-08 04:50:15
问题 I'm trying to make the code below reusable. I need multiple toggle buttons in my flash project. Right now the code below works on one button. If I continue and create more buttons, and follow the format below, I would need to create separate functions for each button. I would like to put the reusable code in a separate ActionScript file and not in the FLA file. I am trying to put the rolloverToggle, rolloverToggle, and toggleClick in a class that I'm making. // ///////////////////////////////

问题 I'm a beginner in OpenCV and would like to print in my console the specific value of a pixel (RGB format) that I define by clicking on it. After some searches I managed to prind the coordinates of the click I make on the image. If anyone knows how to do that please modify this code that I am using: void mouseEvent (int evt, int x, int y, int flags, void* param) { if (evt == CV_EVENT_LBUTTONDOWN) { printf("%d %d\n",x ,y ); } } and this is what I use to call the function: cvSetMouseCallback(

Drawing a rectangle on press and release of mouse, opengl

由 旧街凉风 提交于 2019-12-08 00:23:38
问题 I'm trying to draw a rectangle from user input that collects x1,y1 coordinates from left click, and then specifies x2,y2 from release of the left click. I save the coordinates based on this mouse action successfully (based on cout<< statements confirming the coords are saved) but nothing is displayed after the left button is released. Here is what I've tried: (keep in mind, nothing crashes, so there is a logic error) void display(void) { glClear(GL_COLOR_BUFFER_BIT); glPushMatrix(); glColor3f

NSButton image shadow on mouseEntered event

由 自闭症网瘾萝莉.ら 提交于 2019-12-07 20:16:54
问题 I have a borderless NSButton that contains an image and is subclassed with my ButtonEffect class to detect mouseEntered and mouseExited events. My goal is to have just the edge of the image glow as the mouse enters the button area. I know I can achieve this by using two different images (one with shadow and another without) but I need to do this with one image. Here's an example of what I hope to achieve for the mouseEntered event: And here's what it should look after the cursor leaves the

How to detect a Right Click event in Visual studio?

由 帅比萌擦擦* 提交于 2019-12-07 19:09:31
问题 Okay, so this should be a simple question, but I'm fairly new at programming, and I can't for the life of me figure out how to use a right-click event. All I want to do is call an event that does something when I right-click a picturebox. It's not in the events toolbar, and I feel like a real idiot. Any help would be greatly appreciated. I'm running the 2010 version. 回答1: You can use the mouse_down event and check if it is a right-click Private Sub PictureBox1_MouseDown(Byval sender As Object
