QCombobox und QLineedit

[Momo123]

Hallo,

ich bin noch Anfäger mit Python und GUI und ich suche einen Code mit dem, wenn jemand in Combobox was wählt, dann kommt es automatisch in Lineedit einen Anzahl.

liebe Grüße und vielen Dank!

[__blackjack__]

@Momo123: Sorry der Satz ist irgendwie kein sinnvolles Deutsch. *Was* soll im Lineedit automatisch ”kommen”?

Was hast Du bereits versucht?

[Momo123]

Ich habe eine Liste mit verschiedenen Materialien, die in Combobox sind. Ich will, wenn jemand ein Material davon wählt, dann kommt in Lineedit die Dichte dafür. Die Liste ist ein XML-Schema

[__deets__]

Was hast du schon fuer Code? Bitte code-tags beim posten nicht vergessen.

[Momo123]

unten ist der Code dafür

Du musst das activated()-Signal der Combobox mit dem setText()-Slot des LineEdits verbinden. Diese Verbindung kann man sogar direkt im Designer erzeugen, wenn man möchte.

Übrigens verwendet man heutzutage kein PyQt4 mehr. Das wurde abgelöst durch PyQt5 oder alternativ PySide2.

Auch lässt man normalerweise keinen Python-Code mehr erzeugen, sondern man bindet die Oberfläche mittels loadUi() aus dem PyQt5.uic-Modul ein. Anschließend kann man sich in Python um die nicht-trivialen Verbindungen und den dafür nötigen Code kümmern und alles zusammensetzen - sinnvollerweise in mindestens einer eigenen Klasse, damit man eine gewisse Struktur hat.

Achso, wenn du die passende Dichte ausgeben willst, dann kannst du es nicht mehr unmittelbar an den besagten Slot leiten, sondern solltest einen Callback zwischenschalten und den dann als Slot verwenden.

def Material(self):


base_path = os.path.dirname(os.path.realpath(__file__))

xml_file = os.path.join(base_path, "Data\\MaterialTemplates_v4.xml")

tree = et.parse(xml_file)
root = tree.getroot()







for m in root.findall ('{http://teaser.material}Material'):

i = m.get('material_id')
n = m.find('{http://teaser.material}name')
d = m.find('{http://teaser.material}density')


self.comboBox_Wall1.addItems([n.text])






QtCore.QObject.connect(self.comboBox_Wall1, QtCore.SIGNAL(_fromUtf8("activated(QString)")), self.lineEdit_18.setText)

# so meinst du?
#mit diesem Code bekomme ich bei "lineedit_18" die gleiche Wert wie bei "comboBox_Wall1"

# aber wie verbinde ich lineEdit mit density, wenn ich den Material-Name in Combox wähle ?

@Momo123: Du solltest endlich code-Tags </> verwenden und weniger Leerzeilen. So ist das ja nicht lesbar.
Einbuchstabige Variablennamen sind zu kurz, um aussagekräftig zu sein. Die Materialien solltest Du in einer Datenstruktur speichern, damit Du sie bei einem Change-Event auch setzen kannst. Es gibt findtext.
