In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.
Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The qmake command is executed with the project .pro file."
A block of code is set as follows:
void MemoryWidget::updateSeries()
{
double memoryUsed = SysInfo::instance().memoryUsed();
mSeries->append(mPointPositionX++, memoryUsed);
if (mSeries->count() > CHART_X_RANGE_COUNT) {
QChart* chart = chartView().chart();
chart->scroll(chart->plotArea().width()
/ CHART_X_RANGE_MAX, 0);
mSeries->remove(0);
}
}
When we wish to draw your attention to a particular part of a code block, the relevant lines
or items are set in bold:
windows {
SOURCES += SysInfoWindowsImpl.cpp
HEADERS += SysInfoWindowsImpl.h
debug {
SOURCES += DebugClass.cpp
HEADERS += DebugClass.h
}
}
Any command-line input or output is written as follows:
/path/to/qt/installation/5.11/gcc_64/bin/qmake -makefile -o Makefile project.pro
Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "In Qt Creator, when you click on the Build button, qmake is invoked."
Warnings or important notes appear like this.
Tips and tricks appear like this.
