From 5c83f797c5bcbebe4c2646044f968205980b2350 Mon Sep 17 00:00:00 2001 From: Philip Kaufmann Date: Sun, 24 Jun 2012 18:28:05 +0200 Subject: [PATCH] update QRCodeDialog - remove unused #include 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 --- src/qt/addressbookpage.cpp | 9 ++ src/qt/addressbookpage.h | 3 + src/qt/bitcoingui.cpp | 2 + src/qt/forms/qrcodedialog.ui | 242 +++++++++++++++++------------------ src/qt/guiconstants.h | 6 + src/qt/qrcodedialog.cpp | 87 +++++++++---- src/qt/qrcodedialog.h | 22 ++-- 7 files changed, 217 insertions(+), 154 deletions(-) diff --git a/src/qt/addressbookpage.cpp b/src/qt/addressbookpage.cpp index 5849f5b23d..663ff68669 100644 --- a/src/qt/addressbookpage.cpp +++ b/src/qt/addressbookpage.cpp @@ -2,6 +2,7 @@ #include "ui_addressbookpage.h" #include "addresstablemodel.h" +#include "optionsmodel.h" #include "bitcoingui.h" #include "editaddressdialog.h" #include "csvmodelwriter.h" @@ -20,6 +21,7 @@ AddressBookPage::AddressBookPage(Mode mode, Tabs tab, QWidget *parent) : QDialog(parent), ui(new Ui::AddressBookPage), model(0), + optionsModel(0), mode(mode), tab(tab) { @@ -139,6 +141,11 @@ void AddressBookPage::setModel(AddressTableModel *model) selectionChanged();
