From babd84407a6a3475694268a3966f47a683e4d3cd Mon Sep 17 00:00:00 2001 From: Ken Moore Date: Wed, 5 Oct 2016 17:52:52 -0400 Subject: Add a new Lumina project: desktop-utils/lumina-calculator This is just a very basic calculator at the moment. It still need more buttons/icons/features/etc added to it, but the algorithm and mathematics are already functional for evaluation expressions containing: Addition/Subtraction (+/-) Multiplication/Division( * or x, and /) Order of operations when mixing operations, including expressions within parentheses --- .../lumina-calculator/lumina-calculator.pro | 92 ++++++++++++++++++++++ src-qt5/desktop-utils/lumina-calculator/main.cpp | 19 +++++ src-qt5/desktop-utils/lumina-calculator/mainUI.cpp | 92 ++++++++++++++++++++++ src-qt5/desktop-utils/lumina-calculator/mainUI.h | 33 ++++++++ src-qt5/desktop-utils/lumina-calculator/mainUI.ui | 54 +++++++++++++ 5 files changed, 290 insertions(+) create mode 100644 src-qt5/desktop-utils/lumina-calculator/lumina-calculator.pro create mode 100644 src-qt5/desktop-utils/lumina-calculator/main.cpp create mode 100644 src-qt5/desktop-utils/lumina-calculator/mainUI.cpp create mode 100644 src-qt5/desktop-utils/lumina-calculator/mainUI.h create mode 100644 src-qt5/desktop-utils/lumina-calculator/mainUI.ui (limited to 'src-qt5/desktop-utils/lumina-calculator') diff --git a/src-qt5/desktop-utils/lumina-calculator/lumina-calculator.pro b/src-qt5/desktop-utils/lumina-calculator/lumina-calculator.pro new file mode 100644 index 00000000..8c36c516 --- /dev/null +++ b/src-qt5/desktop-utils/lumina-calculator/lumina-calculator.pro @@ -0,0 +1,92 @@ +include("$${PWD}/../../OS-detect.pri") + +QT += core gui widgets + +TARGET = lumina-calculator +target.path = $${L_BINDIR} + +HEADERS += mainUI.h + +SOURCES += main.cpp \ + mainUI.cpp + +FORMS += mainUI.ui + +LIBS += -lLuminaUtils + +DEPENDPATH += ../../libLumina + +TRANSLATIONS = i18n/l-calc_af.ts \ + i18n/l-calc_ar.ts \ + i18n/l-calc_az.ts \ + i18n/l-calc_bg.ts \ + i18n/l-calc_bn.ts \ + i18n/l-calc_bs.ts \ + i18n/l-calc_ca.ts \ + i18n/l-calc_cs.ts \ + i18n/l-calc_cy.ts \ + i18n/l-calc_da.ts \ + i18n/l-calc_de.ts \ + i18n/l-calc_el.ts \ + i18n/l-calc_en_GB.ts \ + i18n/l-calc_en_ZA.ts \ + i18n/l-calc_es.ts \ + i18n/l-calc_et.ts \ + i18n/l-calc_eu.ts \ + i18n/l-calc_fa.ts \ + i18n/l-calc_fi.ts \ + i18n/l-calc_fr.ts \ + i18n/l-calc_fr_CA.ts \ + i18n/l-calc_gl.ts \ + i18n/l-calc_he.ts \ + i18n/l-calc_hi.ts \ + i18n/l-calc_hr.ts \ + i18n/l-calc_hu.ts \ + i18n/l-calc_id.ts \ + i18n/l-calc_is.ts \ + i18n/l-calc_it.ts \ + i18n/l-calc_ja.ts \ + i18n/l-calc_ka.ts \ + i18n/l-calc_ko.ts \ + i18n/l-calc_lt.ts \ + i18n/l-calc_lv.ts \ + i18n/l-calc_mk.ts \ + i18n/l-calc_mn.ts \ + i18n/l-calc_ms.ts \ + i18n/l-calc_mt.ts \ + i18n/l-calc_nb.ts \ + i18n/l-calc_nl.ts \ + i18n/l-calc_pa.ts \ + i18n/l-calc_pl.ts \ + i18n/l-calc_pt.ts \ + i18n/l-calc_pt_BR.ts \ + i18n/l-calc_ro.ts \ + i18n/l-calc_ru.ts \ + i18n/l-calc_sk.ts \ + i18n/l-calc_sl.ts \ + i18n/l-calc_sr.ts \ + i18n/l-calc_sv.ts \ + i18n/l-calc_sw.ts \ + i18n/l-calc_ta.ts \ + i18n/l-calc_tg.ts \ + i18n/l-calc_th.ts \ + i18n/l-calc_tr.ts \ + i18n/l-calc_uk.ts \ + i18n/l-calc_uz.ts \ + i18n/l-calc_vi.ts \ + i18n/l-calc_zh_CN.ts \ + i18n/l-calc_zh_HK.ts \ + i18n/l-calc_zh_TW.ts \ + i18n/l-calc_zu.ts + +dotrans.path=$${L_SHAREDIR}/lumina-desktop/i18n/ +dotrans.extra=cd i18n && $${LRELEASE} -nounfinished *.ts && cp *.qm $(INSTALL_ROOT)$${L_SHAREDIR}/lumina-desktop/i18n/ + +#desktop.files=lumina-calculator.desktop +#desktop.path=$${L_SHAREDIR}/applications/ + +INSTALLS += target + +WITH_I18N{ + INSTALLS += dotrans +} diff --git a/src-qt5/desktop-utils/lumina-calculator/main.cpp b/src-qt5/desktop-utils/lumina-calculator/main.cpp new file mode 100644 index 00000000..af252cb3 --- /dev/null +++ b/src-qt5/desktop-utils/lumina-calculator/main.cpp @@ -0,0 +1,19 @@ +//=========================================== +// Lumina Desktop source code +// Copyright (c) 2016, Ken Moore +// Available under the 3-clause BSD license +// See the LICENSE file for full details +//=========================================== +#include +#include + +#include "mainUI.h" + +int main(int argc, char *argv[]) { + QApplication a(argc, argv);
