QT on mac


#include <QtGui> //For the GUI components

#include "ui_main_window.h" //generated from QT Designer

void setup_menu_bar(QMainWindow *mw) {
QMenu *fileMenu = mw->menuBar()->addMenu("&File") ;

//QT on Mac automagically moves these to the application menu item because
//they have the strings 'quit', 'about' etc. in them
//(http://doc.trolltech.com/4.4/qmenubar.html#details)

fileMenu->addAction("&About", mw, SLOT(close()));
fileMenu->addAction("&Quit", mw, SLOT(close()));
}

int main(int argc, char *argv[]) {

QApplication app(argc, argv);

QMainWindow *mw = new QMainWindow;

Ui::MainWindow ui;
ui.setupUi(mw);

setup_menu_bar(mw);
//putting this line before setupUi causes menubar to be erased


mw->show();
return app.exec();
}

Python: Multiprocessing: passing multiple arguments to a function

Write a wrapper function to unpack the arguments before calling the real function. Lambda won't work, for some strange un-Pythonic reason.


import multiprocessing as mp def myfun(a,b): print a + b def mf_wrap(args): return myfun(*args) p = mp.Pool(4) fl = [(a,b) for a in range(3) for b in range(2)] #mf_wrap = lambda args: myfun(*args) -> this sucker, though more pythonic and compact, won't work p.map(mf_wrap, fl)

Flowing text in inkscape (Poster making)

You can flow text into arbitrary shapes in inkscape. (From a hint here).

You simply create a text box, type your text into it, create a frame with some drawing tool, select both the text box and the frame (click and shift) and then go to text->flow into frame.

UPDATE:

The omnipresent anonymous asked:
Trying to enter sentence so that text forms the number three...any ideas?
The solution:
Type '3' using the text toolConvert to path using object->pathSize as necessaryRemove fillUngroupType in actual text in new text boxSelect the text and the '3' pathFlow the text
