linux - Using python subprocess.call() to launch an ncurses process -

-

I am trying to call ct-ng () from a SCons SConstruct script, so basically from Python .

Use the following method: 

  ret = subprocess.call (["/ mnt / build / pw_build / crosstool-ng / bin / Ct-ng menuconfig   
 
  crosstool-ng uses ncurses to present the user with a menu:   
 Enter the image details here  
  Unfortunately when I try to get the menu I get what I get:   
 Enter image details here < / P> 
  I see arrow keys Using the cat to display scenes while using:   
 : / mnt / build $ cat> / dev / null ^ [o ^^ ^ [OB ^ [O. O ^ [OB ^ [OD ^ [OC ^ [OY ^ [OB   
 It seems that it is possible to separate the characters who escape the order.  
 When I call the CT-NG script in the terminal from the command line it works correctly, this happens when I  subprocess.call ()  Things are bad Not.  
  My environment includes:   
     
  •  xfce4- Terminal 0.6.3  
  •  Linux 3.13.0-32 -Decor # 57-Ubuntu SMP prepaid Tuesday July 15 04:08:59 UTC 2014 x86_64 x86_64 x86_64 GNU / Linux  
  •  Python 2.7.6  
  •  NCURSES_VERSION "5.9"  
  •  Make GNU 3.81  
  •  CrosTotal-NG Version 1.19.0   
     Am I seeing a known issue? Is there anything else I should do?  
     UPDATE: Thanks Eric .. He got me 0.5 F method. I can navigate the menu now, but still leaves behind drops:  
    > Enter image details here   
     
     
     In order to run a curse program under Python, I recommend that you use it.  
     For example here is a simple program which  vim , add some text, Avoid command mode, issue one: w command, and then interact with user ( Or to continue editing it or whatever) Then the control returns to Python:  
      #! / Usr / bin / env dragon import child = pexpect.spawn ("/ usr / bin / vim") child.send ('a \ n \ nIt is another test.) Child.send (' \ x1b ') Child.send (': w! Test.txt \ n') child.interact ()   
     You can also pass the passed character, and for input and output in the interactive method Filter function. But they get a little harder.  
     (BTW: You can send this desired code to  ct-ng  dialog / menu in your code ... this is just one thing for your terminal settings. For example, for example, a "down arrow" cursor movement ^ "[[[[[E] [bracket] [B]] under MacD X running with Termom = xterm-256color on my item. This will be 'x1b [b' as a python string].

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...

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...

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...
