From 8103b0bb622a927a07d0bbd2696469eb5969e246 Mon Sep 17 00:00:00 2001 From: Philip Kaufmann Date: Mon, 21 May 2012 14:13:16 +0200 Subject: [PATCH] change verifymessagepage behaviour to match RPC-call "verifymessage" (input address, signature and message) / display messages in status label (remove message boxes) / resize window to make signature fully readable / change signature font to BC-address font (like in messagepage) / remove checkAddress() and place code directly in on_verifyMessage_clicked() / add visual feedback to LineEdits / remove AddressTableModel references, as they are now unused / add addr.GetKeyID(keyID) check --- src/qt/bitcoingui.cpp | 2 +- src/qt/forms/verifymessagedialog.ui | 105 ++++++++++++++++------------ src/qt/verifymessagedialog.cpp | 102 +++++++++++++++------------ src/qt/verifymessagedialog.h | 6 +- 4 files changed, 120 insertions(+), 95 deletions(-) diff --git a/src/qt/bitcoingui.cpp b/src/qt/bitcoingui.cpp index a4bb63886..546a39f43 100644 --- a/src/qt/bitcoingui.cpp +++ b/src/qt/bitcoingui.cpp @@ -849,7 +849,7 @@ void BitcoinGUI::changePassphrase() void BitcoinGUI::verifyMessage() { - VerifyMessageDialog *dlg = new VerifyMessageDialog(walletModel->getAddressTableModel(), this); + VerifyMessageDialog *dlg = new VerifyMessageDialog(this); dlg->setAttribute(Qt::WA_DeleteOnClose); dlg->show(); } diff --git a/src/qt/forms/verifymessagedialog.ui b/src/qt/forms/verifymessagedialog.ui index a7c99716e..afe98b05a 100644 --- a/src/qt/forms/verifymessagedialog.ui +++ b/src/qt/forms/verifymessagedialog.ui @@ -6,8 +6,8 @@ 0 0 - 494 - 342 + 650 + 380 @@ -17,7 +17,7 @@ - Enter the message and signature below (be careful to correctly copy newlines, spaces, tabs and other invisible characters) to obtain the Bitcoin address used to sign the message. + Enter the signing address, signature and message below (be careful to correctly copy newlines, spaces, tabs and other invisible characters) to verify the message.
