python - About QTreeView and change selected index -


i use pyqt5.

i use qtreeview qdirmodel list files , folders. 

self.dirmodel = qtwidgets.qdirmodel(self) self.dirtreeview = qtwidgets.qtreeview() self.dirtreeview.setmodel(self.dirmodel)

i want add button change selected index, example, when press button, can select next file in current folder, behavior same press "down" key.

what should do?

you need add button gui, , connect slot clicked event.

 self.button = qtgui.qpushbutton('test', self)         self.button.clicked.connect(self.handlebutton)         // layout existing 1         layout = qtgui.qvboxlayout(self)         layout.addwidget(self.button)      def handlebutton(self):         print ('hello world')

then when have need write code in handlebutton function updates index. qtreeview allows access rows, need row counter , every time increment , ask next row in tree:

indexitem = self.model.index(index.row(), 0, index.parent())  filename = self.model.filename(indexitem) filepath = self.model.filepath(indexitem)

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
