While the primary intention of this pretty printing implementation is
to provide what Qt Creator needs, it can be used in a plain commandline
GDB session, too.
With
python sys.path.insert(1, '<path/to/qtcreator>/share/qtcreator/debugger/')
python from gdbbridge import *
in .gdbinit there is a new "GDB command", called "pp".
With code like
int main(int argc, char *argv[])
{
QString ss = "Hello";
QApplication app(argc, argv);
app.setObjectName(ss);
// break here
}
the "pp" command can be used as follows:
(gdb) pp app
app =
[
<QGuiApplication> = {"Hello"}
staticMetaObject = <QMetaObject> = {""}
[parent] = <QObject *> = {"0x0"}
[children] = <QObjectList> = {"<3 items>"}
[properties] = "<>0 items>"
[methods] = "<6 items>"
[signals] = "<1 items>"
],<QApplication> = {"Hello"}
(gdb) pp app [properties],[children]
app =
[
<QGuiApplication> = {"Hello"}
staticMetaObject = <QMetaObject> = {""}
[parent] = <QObject *> = {"0x0"}
[children] = [
<QObject> = {""}
<QObject> = {""}
<QObject> = {"fusion"}
],<QObjectList> = {"<3 items>"}
[properties] = [
windowIcon = <QVariant (QIcon)> = {""}
cursorFlashTime = <QVariant (int)> = {"1000"}
doubleClickInterval = <QVariant (int)> = {"400"}
keyboardInputInterval = <QVariant (int)> = {"400"}
wheelScrollLines = <QVariant (int)> = {"3"}
globalStrut = <QVariant (QSize)> = {"(0, 0)"}
startDragTime = <QVariant (int)> = {"500"}
startDragDistance = <QVariant (int)> = {"10"}
styleSheet = <QVariant (QString)> = {""}
autoSipEnabled = <QVariant (bool)> = {"true"}
],"<10 items>"
[methods] = "<6 items>"
[signals] = "<1 items>"
],<QApplication> = {"Hello"}
(gdb) pp ss
ss =
<QString> = {"Hello"}
