GXT, how to display the widgets labels with a VBOXLayout - gxt

I have been trying to resolve this by myself but I can't find any answers. I need the text fields the combo box, etc., to display its own label, but I can't put it to work on a panel different from the FormPanel (in which all works great). I'm trying to display the labels for a text field on a VBoxLayout but I don't find the way to do it.
I need to work with a VBoxLayout because I need the widgets to position in the middle of the form after the window is maximized or minimized and this layout is the only one that proves to work. Is there another way to accomplish this?

Add another LayoutContainer and then set the panel to use FormLayout for example
LayoutContainer innerPanel = new LayoutContainer();
innerPanel.setLayout(new FormLayout());
Now it will work just like a form panel.

PYQT Taking a screenshot of a hidden QWidget

I have a QTabWidget with different tabs.
I want to take a screenshot of a hidden tab.
I found out how to create a screenshot of the tab if it's selected now.
The problem is that I want to be able to do that even if another tab was selected.
The solution was very simple in the end, I hope it would help someone if he needs to.
To capture a screenshot of a widget you have in your application, even if it's not currently visible.
For example if you have a number of tabs in your QTabWidget:
# tabs_hash is a dictionary of the widgets we have in the QTabWidget,
# or any widget we have in the application we want to print
for name in tabs_hash:
file = f'{name}.jpeg'
tabs_hash[name].grab().save(file)

PyQt: How to hide everything? (whole application)

Is there a simple way to hide all widgets (essentially hide the whole application)? There are multiple windows and widgets not attached to any window. I'm assuming it's some sort of modifier to the QApplication([]).
EDIT:
Better wording of my question thanks to #eyllanesc:
hide() method that prevents any window (or widget) from showing after using it and you also want the "show" method restore to the previous state.
A possible solution is to iterate over the top level widgets using QApplication::topLevelWidgets() and hide it:
for tl in QtWidgets.QApplication.topLevelWidgets():
tl.hide()
# or
# tl.close()

fltk widget order, button is hide under another widget

I am using fltk 1.3.2.
I have two widgets, one of them is Fl_Multiline_Output and other one is Fl_Button.
The button is a place on the the multiline_output.
When I click multiline_output, the button is disappeared.
I need to use always on top like speciality for my button.
It mustn't be hide.
Does anyone know fltk support this?
I have changed Fl_Multiline_Output to Fl_Text_Display, I put the text and deactivated it. Now, when I click Fl_Text_Display nothing is happen.
I changed to Fl_Text_Display because if I deactivate the Fl_Multiline_Output object, text color is changed. I chose Fl_Text_Display there is no problem with text color.

TextArea without Scrollbars

I have a TextArea in my application that actually takes no interactions from the user.
Is there a way to either
Remove the scrollbar entirely and let me handle what happens when the scrollbar would appear?
Use a different object to display text to the screen? I need to be able to append text, but I don't need it to be highlight-able or take any user input.
According to your needs, you need to use label.
If you need TextArea, to remove scrollBars, you can do the next :
Use lookupAll(java.lang.String selector) method to find scrollBars, and
call scrollBar.setOpacity(0.0) for each found scrollBar.
2a. Don't call setVisible(false), as visible property (I believe) is used to TextArea to control scrollBar visibility.

How do I get action buttons with custom layouts to be styled like standard action buttons in Android 3.0+

I'm having a bit of trouble with custom action buttons in the honeycomb+ action bar. I'm adding a menu item that uses a custom layout (using the android:actionLayout attribute). The reason for the custom layout is that I want a button that has two lines of text that can be updated dynamically.
However, I still want this action button to operate like the other standard buttons. By this I mean that the background fades in when the button is selected, and fades out again if it is unselected, all in the style of the platform (the colour seems to differ between different platforms/devices - I've seen both grey and blue versions)
I've tried using the action button style for the custom layout:
style="#android:style/Widget.ActionButton"
and I've tried setting the background for the custom layout to:
android:background="?android:attr/actionBarItemBackground"
but to no avail, and I'm kind of trying things fairly randomly as I can't find any documentation on how to do this (or if indeed it is even possible).
I know I can approximate this behaviour myself by setting the background, but it would be nice if I could just set the item to behave like a normal action button in terms of how it appears when the user interacts with it.
Anyone have any ideas?
Thanks in advance!
Ah, sorry to answer my own question but I have just stumbled upon a way to do this. I was halfway there - you need your custom layout's style to inherit from ActionButton:
#android:style/Widget.ActionButton
but then you also need to make the layout clickable:
android:clickable="true"
for it to work. Using both of these makes the custom action buttons look just like the regular ones when you press them.
Hopefully that'll help someone trying to do this!
