I am tryimng to make a UI. But in qt, the window size is too short, I want to work in a separate windows like photoshop. Here I am posting the picture. I want to see the middle window(i rounded it by rose color) in full screen size. Can anybody help me?
EDIT:
If I want to create a full screen application, How can I position the widgets in it. It's possible dragging a widget inside a scroll bared window,but is not user friendly. I want it to work like photoshop, like separate windows.
If you want to have more space to work on the design of your widgets, you can open QtDesigner separately and maximize the design area. Panels can be closed and undocked.
Now if you want to maximized only the central widget, there is a trick:
Create a custom widget and work on it in QtDesigner. You will be able to put it in near full screen by increasing its size
Set your custom widget as central widget in your GUI application.
Previous answer before edit:
Hi, If you want to view your widget in fullsreen mode, you can call the ShowFullScreen function. If what you want is to maximize the widget, you can call the ShowMaximized function.

I would like to try make a Dock app using QML (QtQuick) that emulates the animation of the MacOSX dock.
My intention is to make this a Desktop app, and use Mouse Area to detect mouse movements and create the "fish-eye" animation that the MacOSX dock is using.
I was thinking this would be possible using a QML ListView in horizontal mode (or vertical mode):
(see the expandingdelegates.qml:Qt Reference Docs)
Just wanted to get some feedback from experts, can this be accomplished reasonably well with QML? And where to start?
This can be done very easily using qml. You need to study about :
List View
Learn how to create and use
List Models
Learn how to use one and to edit(delete,append) entries in a given model.
Mouse area
Learn how to use and about 'onEntered' and 'onExited' signals.
Scale property
Behavior
Learn how it can be used to provide animations for change in an elements properties.
I think if you are clear with using all the above, you will be able to clearly visualize how to achieve what you are thinking of doing.
I am in process of developing custom GUI generator tool (its new GUI tool like glade) and to achieve that i am using ruby-gtk2. I am a newbie to the world of ruby and gtk, so i need a help in a problem which i am struck regarding adding background image to a widget.
Let me explain in detail, the application (i.e.,GTK::window) has two sections say left section and right section (section can be frames,layouts,panned window or equivalent). Left section has a list of all widgets like Button, Label, CheckBox and so on as images. So user who needs to design the GUI will drag and drop any widgets from left section to right sections, on dropping to right section it (i.e., widget) should be re-sizable and also draggable across right section.
Currently i am adding all widgets to eventbox so that on drag n drop on right section i will get all the controls of events like drag_start, drag_motion, drag_end etc..But how can i add an image as background to eventbox, so that i have button image added to eventbox and also handle resize and drag. Concept is user should be able to resize the properties of widget that drops to right section. Need help in implementing this, i know i am missing something to achieve this. Awaiting any suggestions.
If I subclass QLabel and I add a QLabel directly to my QDialog, it works fine. If I add this label inside a ScrollArea, the thing I’m drawing doesn’t show unless I resize the dialog itself. Yes, weird.
I’ve setup compilable example code that indicates what the problem is. What I am trying to do is to select an area of an image with my mouse, by drawing a rectangle on the corresponding area. The images my program is designed to work with can be very large, and thus, I need to have a scroll area so as the dialog to stay at a logical dimension, and not to fill the entire screen (or even multiple workspaces, if we are talking about a linux machine with multiple desktops).
Everything works fine, except that the drawing (selection-rectangle) isn’t visible unless the dialog is resized – manually. I think I have to update something while drawing, but I’m not sure what. Well, here’s the example code: http://paste.ubuntu.com/1151553/
Another issues that I don’t know how to solve (and I want your suggestions there) are (1) when the user is selecting an area, how to set it to automatically scroll when the user actually selects an area by pushing against to a wall of the scroll area (I guess I am understandable here). (2) is there a way to let the user select a rectangle and then, when he left-clicks on a position with holding down the [Shift] button, the bottom right edge of his previous selection to actually go through the point he clicks at?
The documentation indicates that you have to set a Layout somehow somewhere, but I'm not sure how to do this to my occassion.
Thanks in advance for any help.
about problem (1):
just use of Event. i think mouse Enter Event or Leave Event is good for that.
and to do that i think you can use a hidden rectangular that fill the whole of the screen.
and over write the mouse leave Event for that rectangular and tell in that function , to scroll the page.
I am working on a Cocoa app that consists of 5 views of varying shapes and sizes, some of these views are NSOpenGLViews. I need to have functionality for any of these views to be able to take over the whole window and go into some sort of full screen mode. I originally tried doing this with the method enterFullScreenMode:withOptions: but I ran into trouble when I would try and bring up a dialog window (this would result in a crash). So it seems that I need to scale back my approach a little because I cannot live without these popup dialogs.
My new strategy is to stretch the view that is going into full screen mode so that it takes over the whole view of the screen and then enter into kiosk mode. I was wondering if anyone had tried this type of approach to make a full screen view and if they could offer any advice about best practices for this type of implementation.
My main concern is that I need to preserve the state of the window when I leave full screen mode so I am wondering what would be the best way to hide the other views. Could I just make the other views invisible and then stretch my full screen view to take over the window or would it be better to put the full screen view into a new window and then stretch this new window? My first inclination is that it would be best to keep the full screen view in its original window because it seems this would interfere with event handling less.
I am trying to create an interface for my application using Qt Designer. I want it to have a tabbed, ribbon-style set of controls at the top, and a MDI-style area with docked windows which I plan to show and hide depending on which tab of the ribbon is currently selected. I am just beginning with Qt Designer as well as Qt4 itself for that matter so I'm not quite sure how to setup the window, which widgets and layouts should I use etc.
It's quite obvious there should be a QTabWidget at the top, but I'm not sure about the bottom. Should I use a QFrame? A QMdiArea? A dock widget? What layouts can I use to make sure the tab widget has a fixed height, occupies the whole width of the window at all times and the bottom area scales as the window is resized?
I've read in the manual that splitter layouts allow for manual adjustment of the size of the widgets they contain, but I can't drag the box size of a widget after I place them inside a splitter. Thus I'm unable to setup the area below the ribbon. Anyone, help?
You should look into the QMainWindow and check the multiple utilities it can provide you (Toolbar, StatusBar, DockWidgets, CentralWidget, etc...).
The way I understood your case is that you will always have the MDI Area visible, and that the tab bar will only be used to change the dockWidgets. Here's how I would do it.
The centralWidget of the mainWindow would be a QWidget with a QVBoxLayout containing a QTabBar widget first (up) and a QMdiArea under it. The sizes should be handled automatically.
This will allow the user (or you) to dock widgets on the left, bottom, top or right areas of the mainWindow's central widget. Keep pointers to the dockWidgets to be able to move and show/hide them at will.
Hope this helps.
VTK Designer, which is built on Qt, has a Ribbon-ish interface. You might take a look at the source code for reference.
