changeset 3240:3623795e16dc draft

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
optionsdialog cleanup - remove duplicate includes, that are already present in ui_optionsdialog.h - change QIntValidator to not allow 0 as port-number - re-order some function calls to match the Ui element order, for better readbility and to prepare for the addition of further IPv6 and Tor proxy options - restat warning for the language selection is only shown, when the language was changed (not on simply activating the Ui element) - split check for object == ui->proxyIp into seperate if-clause - micro-optimize the code in the above mentioned if-clause - unify used format for comments in the code - introduce handleProxyIpValid() function, which handles UI elements and the save button states for valid/invalid proxy IPs
