python - QComboBox mouse press event when combo box is initially pressed PyQt4 -

-

i'm trying schedule mouse press event qcombobox. wondering if there way schedule mouse press event on initial qcombobox click -- click brings list of items select. i've used currentindexchanged(int) signal call function once user selects 1 of items drop down menu, i'm trying refresh qcombobox list new entries once user clicks on it. (i have feeling approach may misguided, guess that's question.)

i've tried making qcombobox subclass def mousepressevent(self, e), doesn't seem anything. i've tried def mousepressevent(self, e) in qtgui.qwidget class holds qcomboclass object but, unsurprisingly, captures mouse presses qtgui.qwidget.

your current approach is misguided. if working, fail whenever list opened via keyboard.

the correct way override showpopup:

class combobox(qtgui.qcombobox):     def showpopup(self):         self.insertitem(0, 'added')         super(combobox, self).showpopup()

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
