Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
update QRCodeDialog - remove unused #include <QDebug> and lblBTC label - update Bitcoin input field to a BitcoinAmountField to allow Bitcoin unit selection - use BitcoinUnits::format for the resulting amount parameter in the generated URI (always use BTC as per BIP21) - move MAX_URI_LENGTH and EXPORT_IMAGE_SIZE to guiconstants.h - add OptionsModel in AddressBookPage and use it in on_showQRCode_clicked() to pass it to QRCodeDialog - add OptionsModel in QRCodeDialog to enable display unit updates - add updateDisplayUnit() slot to be able to imediately update currently set bitcoin unit - make all labels in the UI-file plain text - resize dialog to match for an updated layout (fields are now stacked and new field) - remove unused parameters from private slots - only enable save button, when QR Code was generated - show message when entered amound is invalid - add read-only QPlainTextEdit field to output generated URI
