qstatus bar layout -- formatting - qt

My gui have a qmainwindow & with treeview on the left & right side their are some buttons & tableview in the middle of the GUI.
My Qmainwindow gui have an statusbar.
Now i want a horizontal line at top of my statusbar so that it is shown separate from other widgets. (I want a horizontal line running for statusbar just like Toolbar as i have highlighted in red arrow ).
I have attached the picture for it.

You can use a stylesheet to set a top-border to your QStatusBar widget:
setStyleSheet("QStatusBar{border-top: 1px outset grey;}");

Change the location of the QTabBar holding QDockWidgets?

I have a QMainWindow with several QDockWidgets all in the same area, which forces the dock widgets to be tabbed in a QTabBar. The tabs appear at the bottom left corner of the dock area. (In the screenshot the tabs are named "Properties", "Resources", "Attribute Editor", and "Operations".)
Is is possible change where the tabs are located relative to the dock widgets? Specifically, can the tabs be placed above the dock widgets instead of below them?
Use QMainWindow::setTabPosition() method (Qt documentation).
// Will display the tab above the docked widgets in the left side
mainWindow->setTabPosition(Qt::LeftDockWidgetArea, QTabWidget::North);

How to arrange items horizontally in vertical layout?

I have a QWidget with following items aranged in a vertical layout:
- QWidget
- QVBoxLayout
- QPushButton
- QPushButton
- QPushButton
- QListView
- QComboBox
now, I would like to arrange the QComboBox in a horizontal alignment to one of the buttons. I gave the booton a maximumSize of 36 x 16777215 and it sits at the top left of the widget. How Do I get the combo box to align on the right side of it? Here's a screen shot of what I currently have:
Embed your combobox into an horizontallayout and add spacer https://doc.qt.io/archives/2.3/designer/chap4_2.html
You can add a QWidget (or a QFrame) at the top of your vertical layout, then you give this widget (or frame) an horizontal layout and you put your button and your combox box inside this widget with the horizontal layout.

Qt-designer: enlarging the window does not replace my items

To keep the question as simple as possible, I prepared a simple Qt designer form below
There is a Tab Widget on the left side and empty QWidget on the right side, the QWidget as a GroupBox. The Groupbox has a radio and pusbuttons (you can see them on Object inspector window on the photo as well ). The tab widget has a line edit. The central widget has a gridlayout and horizontal qsplitter is used.
My issue is that when I enlarge the window, all items (lineedit, radiobutton, pushbutton) are on the fix position. Here is an example what I mean:
What I want is that when the window is enlarged the items should be placed on the bottom of the window, or if they are in the middle, then they should stay in the middle. ( I don't want size of the buttons/lineedits to be changed).
How can I do it?
The items you want to move dynamically, with window resizing must be in a layout.
So, in the example you've posted, you need two layouts; one inside the tab widget, for the QLineEdit and at least one in the GroupBox for the radio button and push button.
If you want the radio and push button to be aligned horizontally, you can start by placing them in a horizontal layout, before placing that layout in another, which all reside in the group box.
When you start to add items to layouts, such as push buttons, you'll start to notice that they can get stretched, so you may need to set the size policies of the widgets.
If you want the line edit to be centered horizontally, you will have to place two horizontal spacers on each side of the line edit and select the three together and set "Lay out Horizontally". This can found at the top toolbar in Qt Designer.
To always have it at the bottom of the tab widget, put a vertical spacer above the line edit in your tab widget. Then select the option "Lay out vertically" for the tab widget.
The same goes for your radio button and push button. Keep them in a horizontal layout, with horizontal spacers if required and put a vertical spacer into the group box and set the layout property for the group box as "Lay out Vertically".
Most important of all, I suggest you go through some basic tutorials before you continue. Here is a link to a good channel on youtube.

If you don't have a layout in your tabWidget or GroupBox:
You must set a layout (for example QVBoxLayout) inside your tab widget and a group box.
It can be done using QtDesigner. It also can be done in code like this:
QWidget *window = new QWidget;
QPushButton *button1 = new QPushButton("One");
QPushButton *button2 = new QPushButton("Two");
QPushButton *button3 = new QPushButton("Three");
QPushButton *button4 = new QPushButton("Four");
QPushButton *button5 = new QPushButton("Five");
QHBoxLayout *layout = new QHBoxLayout;
layout->addWidget(button1);
layout->addWidget(button2);
layout->addWidget(button3);
layout->addWidget(button4);
layout->addWidget(button5);
window->setLayout(layout);
But if you do, and then you want your buttons to stay at the bottom:
Then you have to try setRowStretch method http://qt-project.org/doc/qt-4.8/qgridlayout.html#setRowStretch or take a look at QSpacerItem.

Center a widget in a layout with Qt Designer

Consider a dialog window:
I want button 1 to be centered horizontally, and button 2 to be in the right corner. How to achieve this?
You can put a horizontal layout that contains a horizontal spacer, pushbutton and another horizontal layout. This second horizontal layout contains a horizontal spacer and a pushbutton.
Something like this:

showing transparent layout over a layout in Qt 4.8.4

I Like to show a label that having a animated gif image over a listwidget.
listwidget is in a horizontal widget. when i am trying to put that label on window it aligned horizontally to list widget. I want to show it over the Listwidget with transparent view.
QMovie *m= new QMovie("loadingImage.gif");
QLabel *l=new QLabel();
ui.mainlayout->add
l->setMovie(m);
m->start();
l->show();
Don’t add the transparent widget to the layout. Just set the window as the transparent widget’s parent then show the widget. You’re then responsible for positioning and resizing the transparent widget to cover the list widget.
