python - PyQt5 draggable frameless window -
i found example set borders on frameless window, it's not draggable. how can make frameless window draggable? if can see example it'll awesome. here example code(normally code longer, that's why there libraries don't mind them);
from pyqt5.qtwidgets import (qmessagebox,qapplication, qwidget, qtooltip, qpushbutton, qdesktopwidget, qmainwindow, qaction, qapp, qtoolbar, qvboxlayout, qcombobox,qlabel,qlineedit,qgridlayout,qmenubar,qmenu,qstatusbar, qtextedit,qdialog,qframe,qprogressbar ) pyqt5 import qtcore, qtwidgets, qtgui pyqt5.qtgui import qicon,qfont,qpixmap,qpalette pyqt5.qtcore import qcoreapplication, qt,qbasictimer import sys class cssden(qmainwindow): def __init__(self): super().__init__() self.mwidget = qmainwindow(self) self.setwindowflags(qtcore.qt.framelesswindowhint) #size self.setfixedsize(320, 450) self.center #label self.lbl = qlabel(self) self.lbl.settext("test") self.lbl.setstylesheet("background-color: rgb(0,0,0);" "border: 1px solid red;" "color: rgb(255,255,255);" "font: bold italic 20pt 'times new roman';") self.lbl.setgeometry(5,5,60,40) self.show() #center def center(self): qr = self.framegeometry() cp = qdesktopwidget().availablegeometry().center() qr.movecenter(cp) self.move(qr.topleft()) app = qapplication(sys.argv) app.setstylesheet("qmainwindow{background-color: darkgray;border: 1px solid black}") ex = cssden() sys.exit(app.exec_())
you need handle mouse events yourself.
- we need add event on
mousepressevent, keep place last clicked on window - then, add
mousemoveevent, calculate distance between last clicked point , current mouse location. move window according distance.
this fixed code:
from pyqt5.qtwidgets import (qmessagebox,qapplication, qwidget, qtooltip, qpushbutton, qdesktopwidget, qmainwindow, qaction, qapp, qtoolbar, qvboxlayout, qcombobox,qlabel,qlineedit,qgridlayout,qmenubar,qmenu,qstatusbar, qtextedit,qdialog,qframe,qprogressbar ) pyqt5 import qtcore, qtwidgets, qtgui pyqt5.qtgui import qicon,qfont,qpixmap,qpalette pyqt5.qtcore import qcoreapplication, qt,qbasictimer, qpoint import sys class cssden(qmainwindow): def __init__(self): super().__init__() self.mwidget = qmainwindow(self) self.setwindowflags(qtcore.qt.framelesswindowhint) #size self.setfixedsize(320, 450) self.center() #label self.lbl = qlabel(self) self.lbl.settext("test") self.lbl.setstylesheet("background-color: rgb(0,0,0);" "border: 1px solid red;" "color: rgb(255,255,255);" "font: bold italic 20pt 'times new roman';") self.lbl.setgeometry(5,5,60,40) self.oldpos = self.pos() self.show() #center def center(self): qr = self.framegeometry() cp = qdesktopwidget().availablegeometry().center() qr.movecenter(cp) self.move(qr.topleft()) def mousepressevent(self, event): self.oldpos = event.globalpos() def mousemoveevent(self, event): delta = qpoint (event.globalpos() - self.oldpos) #print(delta) self.move(self.x() + delta.x(), self.y() + delta.y()) self.oldpos = event.globalpos() app = qapplication(sys.argv) app.setstylesheet("qmainwindow{background-color: darkgray;border: 1px solid black}") ex = cssden() sys.exit(app.exec_())
