Hello again, BTW using this method you can put args in quotes too like QString( "cscript C:\\progra~1\\yourpath\\your_vbs.vbs \"%1\" \"%2\" \"%3\" \"%4\"" ).arg( arg_var_0).arg(arg_var_1).arg(arg_var_2).arg(arg_var_3); Happy coding, Emre On Tue, Mar 10, 2015 at 9:27 PM, NoMercy wrote: > Hello,

Re: [Interest] What is the best way to refresh QML image

Hi Harry, If you want a low-tech, QML-only workaround, perhaps you could have 2 Images at the same location with the same dimensions, and just switch between them when a refresh occurs. You could stage the refreshed picture into the currently invisible, source-less Image, then set it to visibl

One last thing. I am trying to start the VBS with: p->startDetached("go.vbs", arguments); However, this returns false and does not start the vbs. I see that you use cscript to start yours, but you do not pass any arguments. How would that be accomplished? Basically, in the line above, the a

[Interest] ListView.currentIndex

ListView currentIndex behavior is bit of a mystery to me. I have a StackView where one page has a ListView. If I leave the page and come back to it, it seems that the currentIndex is somehow stuck and does no longer update when I scroll the list. Only when I reinitialize the ListView model,

Well, reading the thread it seems that options are: 1. changing the "source" property, which feels like a hack if used directly. 2. setting cache=false and calling sourceChanged(), but it was not clear from the thread if this works or not. 3. implementing a custom item to replace Image, which fee

Hello. When you create a widget with no parent, it becomes a separate window. So, you're creating 200 (native) windows and then destroy them when you put a widget in a list. Creating native controls is a very slow operation. Try passing a view as a parent for UserControl. Next, what is real useca
