I’m trying the sketch.jl example from the Tk.jl package: On OS X this gives a drawing canvas that is only updated when I switch windows, i.e., force the drawing to be updated. When I add an explicit Tk.update() after line 27, I get spurious lines in the drawing: [image] Anyone knows how to solve…

With linux i can sketch. When i switch windows (MAP/UNMAP in X11) i get a sigfault…

Gtk.jl does the job! using Gtk.ShortNames, Graphics function sketch_window() widget = @Canvas() window = @Window(widget, "MyCanvas") lastx = 0; lasty = 0; widget.mouse.button1press = @guarded function (widget, event) lastx = event.x; lasty = event.y end widget.mo…

I was about to mention this (use Gtk), but you sounded like, you’re focused on Tk…

I was just trying out some of the possibilities for designing a GUI with Julia. Other comments/tricks I should know about are welcome :slight_smile:

I couldn’t resist taking a stab at this with QML.jl :slight_smile: Julia code: https://github.com/barche/QML.jl/blob/master/example/sketch.jl QML file: https://github.com/barche/QML.jl/blob/master/example/qml/sketch.qml

~20 lines vs. ~40 lines → Gtk is more efficient (SCNR)

Yes, but on the other hand you get clean separation between GUI (the QML) and data (just the Point here). The QML file, which is the longest, could easily be generated using a GUI designer such as Qt Creator.

I’m not seriously (SCNR-> sorry, could not resist…) comparing the efficiency of different UI toolkits. We see convergence here: Similar code for similar problems. btw: about the code and GUI split: GtkBuilder exists and you can do an xml desciption of a GUI or build it with glade and run it or chan…

Yes, I figured as much (though I had to google SCNR) :slight_smile: It’s good to have options for sure, as there is no “one size fits all”.

I’m a gtk user and apart from some BinDeps problems quite satisfied. Recently we had this GUI thread: Julia for GUI app with other ideas for GUI implementations.
