Hello, I've installed octave 3.6.2 on windows XP. And I try to use the function "ginput" : imshow(rand(100)) [x,y]=ginput(1) But I get this error: error: feval: function '__qt_ginput__' no found error: called from: error: <>\m\plot\ginput.m at line 41, column 21 Does anyone have an idea? Thanks Héctor. -- View this message in context: http://octave.1599824.n4.nabble.com/ginput-doesn-t-work-tp4646576.html Sent from the Octave - Dev mailing list archive at Nabble.com. |

Hi Héctor, I'm not exactly sure because this works on a fairly recent development version on my linux system. I am using gnuplot for the graphics and get a toolkit description of octave:3> toolkit = (get (gcf, "__graphics_toolkit__")) toolkit = gnuplot for both command line interface and GUI. From the error message you've shown, you should get a toolkit description of "qt". I've searched the script codes in the source tree and don't immediately see how "qt" could end up in your figure structure. What graphics are you using on your Windows XP system? Is it gnuplot, fltk, something else? (I ask because I haven't much experience with how Octave behaves under Windows.) If you don't know that, please describe what the window containing the image of random grey pixels looks like. Dan |

Hello Dan, Thanks for reply me. My graphics type is a: "Mobile Intel(R) 965 Express Chipset Family". Just to be more precise, I installed this version of octave "Octave 3.6.2 for Windows Microsoft Visual Studio".

Too precise. :-) > Just to be more precise, I installed this version of octave "Octave 3.6.2 > for Windows Microsoft Visual Studio". Octave uses a graphics engine to draw the figures. What we mean by "engine" at this level is a different program that draws the lines, fonts, etc. for display on the screen. "gnuplot" means that Octave is using gnuplot plotting program to create figures. "fltk" means that Octave is using a drawing library. "qt" (what you are seeing) would mean that some form of the Qt user-interface tools is being used. Please describe what your window looks like that contains the grayscale image created by your "image" command. Are there some icons? If so what do those icons look like? Dan |

Hello, Sorry for the mistake. I've just started working with octave. First, I installed octave with the default parameters : "Toolkit = qt". I have just uninstalled and reinstalled it but this time I chose "Gnuplot" as graphics toolkit and the problem is solved. Thanks a lot.

You run the qthandles toolkit which has no implementation for ginput, switch to one of the others and try with that close all graphics_toolkit fltk for example at the octave prompt (you may need to close all graphics before with the close all). |

Ah, I now see where the "qt" originated from. Dan |

Just curious why you chose Qt initially. Would you like the Qt interface on your system? One thing we are attempting at the moment is using Qt toolkit via gnuplot. In linux, it works. Windows, we suspect not.

What I'm referring to basically requires a recent version of gnuplot having "qt" terminal support and set the environment variable GNUTERM to "qt". (The Windows--and some Apple OSX--issue is fork.)
