I am trying to setWindowFlags (no maximize) and to make my subwindow NOT resizable, but setWindowFlags and setFixedSize are not doing it. No error messages. Everything else works. Here's a simplified version of my code. Thanks.
Main window - main.py
from PyQt5 import QtCore
from PyQt5.QtWidgets import QMainWindow, QApplication, QAction, QMdiArea, QDesktopWidget, QMdiSubWindow
import usuarios
import sys
class MainWin(QMainWindow):
def __init__(self, parent=None):
super(MainWin, self).__init__(parent)
self.setupUI()
self.setMinimumSize(1100, 600)
area = self.frameGeometry()
center = QDesktopWidget().availableGeometry().center()
area.moveCenter(center)
self.move(area.topLeft())
def setupUI(self):
self.setGeometry(0, 0, 1050, 600)
self.mdi = QMdiArea()
self.toolBarItem = self.addToolBar("File")
self.myAction = QAction("Usuários", triggered=self.showFormUsers)
self.toolBarItem.addAction(self.myAction)
self.setCentralWidget(self.mdi)
def showFormUsers(self):
self.subWindow = usuarios.formUsers()
self.mdi.addSubWindow(self.subWindow)
self.subWindow.setWindowFlags(QtCore.Qt.WindowMinimizeButtonHint | QtCore.Qt.WindowCloseButtonHint) # No effect. The maximize button still appears.
self.subWindow.setFixedSize(480, 300) # No effect. I can still resize the subwindow
self.subWindow.show()
if __name__ == '__main__':
app = QApplication(sys.argv)
win = MainWin()
win.show()
sys.exit(app.exec_())
Subwindow - usuarios.py
from PyQt5 import QtCore, QtWidgets
from PyQt5.QtWidgets import QMainWindow
class formUsers(QMainWindow):
def __init__(self, parent=None):
super(formUsers, self).__init__(parent)
self.setWindowTitle("Usuários")
# Input Fields ---------------------------------------------------------- >
self.lineEdit_name = QtWidgets.QLineEdit(self, placeholderText="Name")
self.lineEdit_name.setGeometry(QtCore.QRect(70, 80, 331, 20))
self.lineEdit_name.setObjectName("lineEdit_name")
self.lineEdit_login = QtWidgets.QLineEdit(self, placeholderText="Login")
self.lineEdit_login.setGeometry(QtCore.QRect(70, 110, 113, 20))
self.lineEdit_login.setObjectName("lineEdit_login")
self.lineEdit_pwd = QtWidgets.QLineEdit(self, placeholderText="Password", echoMode=2)
self.lineEdit_pwd.setGeometry(QtCore.QRect(70, 140, 113, 20))
self.lineEdit_pwd.setObjectName("lineEdit_pwd")
# Push Buttons ---------------------------------------------------------- >
self.pushButton_first = QtWidgets.QPushButton(self)
self.pushButton_first.setGeometry(QtCore.QRect(50, 210, 75, 23))
self.pushButton_first.setObjectName("pushButton_first")
self.pushButton_first.setText("<< First")
self.pushButton_previous = QtWidgets.QPushButton(self)
self.pushButton_previous.setGeometry(QtCore.QRect(140, 210, 75, 23))
self.pushButton_previous.setObjectName("pushButton_previous")
self.pushButton_previous.setText("< Previous")
self.pushButton_next = QtWidgets.QPushButton(self)
self.pushButton_next.setGeometry(QtCore.QRect(230, 210, 75, 23))
self.pushButton_next.setObjectName("pushButton_next")
self.pushButton_next.setText("Next >")
self.pushButton_last = QtWidgets.QPushButton(self)
self.pushButton_last.setGeometry(QtCore.QRect(330, 210, 75, 23))
self.pushButton_last.setObjectName("pushButton_last")
self.pushButton_last.setText("Last >>")

Is there a special reason to use pymysql?
Python has sqlite3 and PyQt5 has QtSql.

I have a MySQL database on my local machine and I read I could use pymsql to connect to it.

Often you don't need any extra modules at all. See here what python has to offer.

My MDI application used to have all the code in one single file and everything worked, but now that I split the code I can't set the subwindow flags and its fixed size. No error messages. The subwindow opens just as if the code was no there. Everything else works exactly that way I want. The Mdi is in main.py and the subwindow in usuarios.py. Any ideas? Here's the code for both files. Thanks.
import usuarios
line 3, in <module>
import usuarios
ModuleNotFoundError: No module named 'usuarios'

Still can't get rid of the maximize button and fix the subwindow size... I simplified the code so it's easier to understand:
main.py
from PyQt5 import QtCore
from PyQt5.QtWidgets import QMainWindow, QApplication, QAction, QMdiArea, QDesktopWidget, QMdiSubWindow
import usuarios
import sys
class MainWin(QMainWindow):
def __init__(self, parent=None):
super(MainWin, self).__init__(parent)
self.setupUI()
self.setMinimumSize(1100, 600)
area = self.frameGeometry()
center = QDesktopWidget().availableGeometry().center()
area.moveCenter(center)
self.move(area.topLeft())
def setupUI(self):
self.setGeometry(0, 0, 1050, 600)
self.mdi = QMdiArea()
self.toolBarItem = self.addToolBar("File")
self.myAction = QAction("Usuários", triggered=self.showFormUsers)
self.toolBarItem.addAction(self.myAction)
self.setCentralWidget(self.mdi)
def showFormUsers(self):
self.subWindow = usuarios.formUsers()
self.mdi.addSubWindow(self.subWindow)
self.subWindow.setWindowFlags(QtCore.Qt.WindowMinimizeButtonHint | QtCore.Qt.WindowCloseButtonHint) # No effect. The maximize button still appears.
self.subWindow.setFixedSize(480, 300) # No effect. I can still resize the subwindow
self.subWindow.show()
if __name__ == '__main__':
app = QApplication(sys.argv)
win = MainWin()
win.show()
sys.exit(app.exec_())usuarios.py
from PyQt5 import QtCore, QtWidgets
from PyQt5.QtWidgets import QMainWindow
class formUsers(QMainWindow):
def __init__(self, parent=None):
super(formUsers, self).__init__(parent)
self.setWindowTitle("Usuários")
# Input Fields ---------------------------------------------------------- >
self.lineEdit_name = QtWidgets.QLineEdit(self, placeholderText="Name")
self.lineEdit_name.setGeometry(QtCore.QRect(70, 80, 331, 20))
self.lineEdit_name.setObjectName("lineEdit_name")
self.lineEdit_login = QtWidgets.QLineEdit(self, placeholderText="Login")
self.lineEdit_login.setGeometry(QtCore.QRect(70, 110, 113, 20))
self.lineEdit_login.setObjectName("lineEdit_login")
self.lineEdit_pwd = QtWidgets.QLineEdit(self, placeholderText="Password", echoMode=2)
self.lineEdit_pwd.setGeometry(QtCore.QRect(70, 140, 113, 20))
self.lineEdit_pwd.setObjectName("lineEdit_pwd")
# Push Buttons ---------------------------------------------------------- >
self.pushButton_first = QtWidgets.QPushButton(self)
self.pushButton_first.setGeometry(QtCore.QRect(50, 210, 75, 23))
self.pushButton_first.setObjectName("pushButton_first")
self.pushButton_first.setText("<< First")
self.pushButton_previous = QtWidgets.QPushButton(self)
self.pushButton_previous.setGeometry(QtCore.QRect(140, 210, 75, 23))
self.pushButton_previous.setObjectName("pushButton_previous")
self.pushButton_previous.setText("< Previous")
self.pushButton_next = QtWidgets.QPushButton(self)
self.pushButton_next.setGeometry(QtCore.QRect(230, 210, 75, 23))
self.pushButton_next.setObjectName("pushButton_next")
self.pushButton_next.setText("Next >")
self.pushButton_last = QtWidgets.QPushButton(self)
self.pushButton_last.setGeometry(QtCore.QRect(330, 210, 75, 23))
self.pushButton_last.setObjectName("pushButton_last")
self.pushButton_last.setText("Last >>")

The problem is using QMainWindow as SubWindow, use QMdiSubWindow
change the first lines in usuarios.py to
from PyQt5 import QtCore, QtWidgets
from PyQt5.QtWidgets import QMdiSubWindow
class formUsers(QMdiSubWindow): and in main.py
def showFormUsers(self):
self.subWindow = usuarios.formUsers()
self.subWindow.setFixedSize(480, 300)
self.mdi.addSubWindow(self.subWindow)
self.subWindow.show()
