add Widgets in widgets

[WingMan]

Hi,
my problem is to insert some widgets in one "main" widget (not MainWindow!).
I built a widget by using Qt designer (e.g. widget1) and created a class (widget2) to implement some functions for widget1.
In the next step I created a new widget (widget3) which has only a tableWidget inside.

My Problem is, if I create another widget (widget4) in which I want to place those two widgets (wiget2, widget3) there is nothing to see in widget4.

Here is my code of widget4:


require 'Qt4'
require 'Widget2'
require 'Widget3'

class Widget4 < Qt::Widget
def initialize()
super()

@layout = Qt::VBoxLayout.new()

@widget2 = Widget2.new
@widget3 = Widget3.new
@layout.addWidget(@widget2)
@layout.addWidget(@widget3)

setLayout(@layout)
size = Qt::Size.new(500, 500)
size = size.expandedTo(minimumSizeHint())
resize(size)
end
end

Hope u can help me,

THX

How are you adding widget4 ??
if u want widget2 and widget3, u need to set them in layout... something ilke -


QHBoxLayout *lay4 = new QHBoxLayout;
lay4->addWidget(widget2);
lay4->addWidget(widget3);
widget4->setLayout(widget4);

layout->addWidget(widget4);
setLayout(layout);

My fault, forgot to mention: Programming in ruby not in C++!
I add those two Widgets in a layout by

@layout.addWidget(@widget2)
@layout.addWidget(@widget3)

And widget4 is the widget which has to display the layout with widget2 and 3 so I thoght I don't need to add it into the layout???

Your code looks OK. What happens if you replace widget2 and widget3 with QPushButtons?

The problem seems to be widget2. Without widget2 everything looks fine!
How can I add a widget (widget2) which inherits from a widget which is created by Designer(widget1)?
my way:
widget 2:


@a = Ui::XYZ.new() #new instance of widget1
@a.setupUi(self)

and add widget2 in widget 4


@widget2 = Widget2.new(self)
@layout.addWidget(@widget2)


But there is nothing to see.
Without the layout, widget2 is shown in wdget4, but... without layout-management!
