Read all widgets from the loaded .ui file
-
hi guys,
I would like to get all the widgets that are presented in .ui loaded file.
So I am loading the file like this:
@QUiLoader loader;
QFile file(fname);
file.open(QFile::ReadOnly);
QWidget *myWidget = loader.load(&file, this);
file.close();@And afterwards I do not know how to get the list of widgets.
Any help really appreciated. -
Do you mean you want instances of them, QObject names of them or the classes names?
myWidget is a QObject like any other. You can get the children list via "children()":http://qt-project.org/doc/qt-5/qobject.html#children
You can also get the widget's "layout":http://qt-project.org/doc/qt-5/qwidget.html#layout and then "each item in it":http://qt-project.org/doc/qt-5/qlayout.html#itemAt and so forth.
QUIloader has also methods for obtaining names of classes and layouts in the file.

Hi Chris,
Thanks for respond.
I have played around with children method.
I guess, I would like to have QObject names, since I want to know which widget they are to work further with them.
But children() gives me a lot other widgets like scroolarea_hcontainer, scrollarea_vcontainer and others,
but I have only QLineEdit, and QPushButton, and I would like to get only these two objects.
Can you please show me how I can get widgest layout and each item in it? I guess it will give what I am searching?Thanks forward.

You can use the methods I already linked for traversing layouts if you want to know the structure (what is in which container etc.).
@
//Pack it into recursive function
QLayout *layout = myWidget->layout();
if (layout) {
for (int i = 0; i < layout->count(); ++i) {
QWidget w = layout->itemAt(i)->widget();
if(w)
//do smthn with w or go deeper via w->layout()
}
}
@You can also use something like this to get all children of specific type.
@QList<QLineEdit*> lineEdits =
myWidget->findChildren<QLineEdit*>()
QList<QPushButton*> btns =
myWidget->findChildren<QPushButton*>()
@
Through that you can of course iterate and get all the names.
