python - When using an event in Tkinter, how can you pass in other variables to the event function? -

    इस उदाहरण में, कि मैं से उपयोग किया जाता है, आप फ़ंक्शन कॉलबैक के लिए अधिक चर में कैसे पारित कर सकते हैं मान लीजिए कि आप उस डिक्ट में पारित करना चाहते थे जिसे आपने बनाया और उस शब्द का इस्तेमाल किया, आप वैश्विक चर को बिना कॉल कैसे कर सकते हैं। Tkinter import * root = Tk () def callback (event) : Print "clicked at", event.x, event.y फ्रेम = फ़्रेम (रूट, चौड़ाई = 100, ऊंचाई = 100) फ्रेम.बिंद ("& lt; बटन-1 & gt;", कॉलबैक) frame.pack () रूट। मेनब्लूप ()

    न्यूबेस में, कुछ अजीब शब्द-कथन हो सकते हैं, स्पष्टीकरण मांगने में संकोच न करें।

    यहां दो संभावित तरीके हैं।

    1. आप अपने 'कॉलबैक' फ़ंक्शन को एक वर्ग में रख सकते हैं, और स्व-परिभाषित चर में पास करने के लिए स्वयं का उपयोग कर सकते हैं
    2. आप अपने सभी चर को अन्य मॉड्यूल फ़ाइल में सेट कर सकते हैं और उसे इस फ़ाइल में आयात कर सकते हैं। चूंकि किसी अन्य फ़ाइल के चर को इस नेमस्पेस में आयात किया गया है, इसलिए आप उन्हें 'कॉलबैक' फ़ंक्शन में बिना गुजर सकते हैं, केवल वैश्विक वैरिएबल के समान।

c# - Textbox not clickable but editable -

-
I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...
