qt - Resize QDialog when RadioButton is Checked PyQt -


not many experience @ pyqt..

i have designed ui qt designer 2 radiobuttons.

depending on radiobutton selected widgets visible , other not. i'm not trying resize automatically layout of dialog depending on how many widgets visible in ui.

the question similar this one . here extract of code might helpful understand problem (i know piece of code, entire dialog pretty long):

class mydialog(qdialog, form_class):     ..........      # connect radiobutton function reloads ui     self.radiosingle.toggled.connect(self.refreshwidgets)       .....      # dictionary widgets , values     self.widgettype = {             self.cmbmodelname: ['all'],             self.cmbgridlayer: ['all'],             self.cmbriverlayer: ['all'],             self.linenewlayeredit: ['all'],             self.linelayernumber: ['single']         }  # function refresh ui correct widgets depending on radiobutton selected     def refreshwidgets(self, idx):         '''         refresh ui widgets depending on radiobutton chosen         '''           tp = self.radiosingle.ischecked()          k, v in self.widgettype.items():             if tp:                 if 'all' or 'single' in v:                     active = true                 k.setenabled(active)                 k.setvisible(active)             else:                 active = 'all' in v                 k.setenabled(active)                 k.setvisible(active)          # attempt resize dialog         self.setsizeconstraint()

surely code improved (not skilled code writing)...

you gotta set_up ui resize when it's needed. there lot of more beautiful way this, here simple , fast example:

you have define layout behave way want. if make use of minimum , maximum size it'll resize need. have own personalized buttons, widgets, .... have cleaner code.

observe i'm using pyqt5, if need gotta change imports version using.
