Grid within a frame?

我怕爱的太早我们不能终老 提交于 2019-11-28 00:16:36
问题 Is it possible to place a grid of buttons in Tkinter inside another frame? I'm wanting to create a tic-tac-toe like game and want to use the grid feature to put gamesquares (that will be buttons). However, I'd like to have other stuff in the GUI other than just the game board so it's not ideal to just have everything in the one grid. To illustrate: O | X | X | ---------- | O | O | X | Player 2 wins! ---------- | X | O | X | The tic tac toe board is in a grid that is made up of all buttons and

How could I get a Frame with a scrollbar in Tkinter?

I'd like to have a Frame , where the user could add as many textfields as needed by the application. The application starts with a textfield, and a button below that textfield. When the user presses the button, a new text entry will be added below the first one ( this may be repeated countless times ). In the middle of the window, there will be a Text widget, used to display text :) However, I noticed this in the documentation: This widget is used to implement scrolled listboxes, canvases, and text fields. Is there a way to use the Scrollbar with a Frame ? If you can use Tix, there is the

How to extract frames of an animated GIF with PHP

冷暖自知 提交于 2019-11-27 20:17:26
I search for a long time how to extract frames from an animated GIF with PHP... unfortunaly I just found how to get their duration... I really need to extract the GIF frames and their duration to apply some resize, rotate, etc, on each and then to regenerate the GIF with edited frames ! I don't want to use any software, external library (like ImageMagick), just PHP: in fact I need to allow my class http://phpimageworkshop.com/ to work with animated GIF. If you have any idea, I'm listening you ^^ ! Sybio I spent my day creating a class based on this one to achieve what I wanted using only PHP!

I have an UIImageView in the self.view (the main View) and inside it there is a UIButton . I want to know what's the frame of UIButton in self.view not in UIImageView . I guess you are looking for this method – convertRect:toView: // Swift let frame = imageView.convert(button.frame, to: self.view) // Objective-C CGRect frame = [imageView convertRect:button.frame toView:self.view]; jbat100 There are four UIView methods which can help you, converting CGPoints and CGRects from one UIView coordinate reference to another: – convertPoint:toView: – convertPoint:fromView: – convertRect:toView: –

问题 How to know total number of Frame in a file ( .avi) through Python using open cv module. If possible what all the information (resolution, fps,duration,etc) we can get of a video file through this. 回答1: With a newer OpenCV version (I use 3.1.0) it works like this: import cv2 cap = cv2.VideoCapture("video.mp4") length = int(cap.get(cv2.CAP_PROP_FRAME_COUNT)) print( length ) And similar for other video properties cv2.CAP_PROP_* 回答2: import cv2 cap = cv2.VideoCapture(fn) if not cap.isOpened():

Adding label to frame in Tkinter ignores the attributes of frame

折月煮酒 提交于 2019-11-27 09:33:38
I have created a frame of fixed size and now i want to add some labels and other widgets on it. But i observed as soon as i add new widget on this frame its attributes are not honored i.e. size and default back ground color set is not honored. from Tkinter import * tk = Tk() page1 = Frame(tk, bg="blue", width=100, height=200) l1 = Label(page1, text='This is label 1') page1.pack() l1.pack() tk.mainloop() So in the above example if i comment out line 4 & 6, then i can see a frame of fixed size with blue background color. My requirement is I want to add some other widgets on this frame with this

Accessing the document object of a frame with JavaScript

I'm testing on this page , and I'm not sure what I'm missing. // Two frames on the page > document.getElementsByTagName("frame").length 2 // Same domain, so no security restrictions > document.getElementsByTagName("frame")[0].src "http://www.quackit.com/html/templates/frames/menu_1.html" > window.location.href "http://www.quackit.com/html/templates/frames/frames_example_1.html" // Can't access the document > document.getElementsByTagName("frame")[0].document undefined It seems like this should work, so what's the problem? It needs to work in IE8, but I'm also testing in Chrome (newest stable).

tkinter gui layout using frames and grid

社会主义新天地 提交于 2019-11-27 07:39:01
My gui layout looks almost nothing like what I expect so I assume there are some basics that I don't understand. I assumed that frames contain their own 'grid space' (row, column) but the behavior I see doesn't bear that out, and I'm at a loss for getting things working the way I want for the top frame. My labels are supposed to be on the same row L to R, under a 'frame label' that spans the entire frame - except they don't. I want the actual to look more like the goal jpg, and I want to use grid to do it. You can just see one of the entry fields to the right of the green frame. Why is it

问题 I need to display another external site's content into my site. Normally <iFrame> tag can do it. But my requirement is not whole content, only part of that site.

I tried $("$my-content").load("http://www.anothersite.com #load-content") , but not working. 回答1: This is due to ajax cross domain security restrictions, one trick is

How do you do transition effects using the Frame control in WPF?

不问归期 提交于 2019-11-27 06:50:39
I thought this would be easy but I guess not. I have 2 pages that load in my frame control. I want to be able to either have a nice slide effect from one page to the next or just a simple fade-In effect. Can't seem to find this anywhere on the internets. Update 1 The accepted answer is good, but I found an even better one here. http://www.japf.fr/2008/07/8/comment-page-1/ Update 2 If you can believe it I found an even better solution. http://fluidkit.codeplex.com/ There is a similar problem discussed here: Transition Fade Animation When Navigating To Page Using the technique described there
