Button.Caption "einfrieren"?
 
Hallo liebes Forum,

Gibt es in Delphi einen Befehl, mit dem man die Caption eines Buttons "einfrieren", also dass die Caption "unantastbar" und unter gar keinen Umständen zu ändern ist?

Hallo und willkommen in der DP :dp:

Als erstes leider ein Mini Anpfiff. Crossposts bitte in Zukunft gegenseitig verlinken damit Antworten nicht doppelt gegeben werden bzw. ein Forum die Lösung schon hat im anderen noch darüber geschwitzt wird. 8-)

Zum Thema:
Kannst du dein Anliegen etwas genauer definieren ? Wenn du in deinem Programm die Caption nicht änderst bleibt sie auch so. Oder meinst du von Extern ? Wer sollte so etwas versuchen ?

Keinen Befehl.
Aber was hält dich davon ab dieses selbst auf den Button zu zeichnen?

Edit: Ich möchte, dass sobald ein Button die richtige Caption (also die richtige Zahl [1-9]) hat, die Caption nicht mehr von den anderen Buttons geändert werden kann.

Ich gebe euch mal meinen Quellcode... ^^

Ähmmm... ok. :roll:

Versuche mal zu beschreiben (Stichpunkte) wie dein Programm arbeiten soll. Bevor das nicht klar ist, können wir schlecht helfen.

Japp, sehe ich auch so. Dann kann man auch gleich Logik und Darstellung trennen, denn Buttons sind ja nicht dazu da, irgendwelche Daten vorzuhalten, sondern um ein Ereignis auszulösen. Und wenn man doch unbedingt Daten darin verwalten will/muss, eignet sich die Tag-Eigenschaft wohl eher dazu, zumal sie auch noch zufällig nummerisch ist.

Was ist denn die "richtige" Zahl für einen Button?

Denke mal das soll eine art Slottmachine sein.
Wobei wenn eine zahl zwischen 1 und 9 auftritt diese nicht mehr geändert werden soll.

Nur geraten.

Hmmm, was könnte bei

Random(9)+1
wohl an Zahlen herauskommen...
