MDI application with multiple Forms
-
look here
@Gerd I have looked into the example, it is more of a text editor which can be invoked multiple times, My requirement is invoking of predetermined and pre designed UI forms with a selection of text fields for editing and saving information into a data source. I will look into the example again and see if I can get some help with the problem I am working on.
looks like the terminology used is slightly different to the one used in .net development, hopefully I could clarify.
Thank you. -
Hi
It sounds like something stackedwidget would work for.
These different forms-will they need to be shown at same time inside app, or will it always be just one that is visible? and u can navigate between them inside the app/same area.try this fast sample
it has stacked and 3 forms it switches between.

@mrjj Hi, I looked into the code you shared, it is not what I had in mind, I need the application to be menu driven.
I should be able to choose the UI form based on the user selection in the menubar.
For example I want to have Appmenu under which I will have the options, Login, form1, form2, form3, Logout, Exit.So at the app start the user will be shown the login form and once he logs in he will be able to choose any one of the forms from the menu or all the forms available in the menu.
I would say the Login, form1, form2, form3 are all mdichild forms which are contained within the MDIParent whenever invoked. I am yet to come across an example which explains the process.
I am not sure if stacked widgets is going to help me with that.
The MDI example available with the Qt package doesnt use forms UI as it is a text editor, which has a MDI parent and the text editors being the MDI Childs. wish Qt had an example along the similar lines but with forms.
Thanks for looking into the issue, if you find a solution please do post.

@Nishanth said in MDI application with multiple Forms:

Well, it uses QTextWidget (I guess), which is a QWidget at the end. Just put your own widget there instead of the text edit.

@jsulm I have explained why the MDI example doesn't provide the required solution to my problem in the previous threads. If it was just one widget as you told I would have got it over with, My requirement is multiple controls (widgets) which comprises of multiple text boxes and buttons in a UI form. and I have multiple UI forms.

@Nishanth I know. The thing is: all these widgets you are talking about are placed on some widget (parent widget), right? So, create a custom widget where you put all these widgets and then put this custom widget (parent widget) where you need it...

@jsulm I have placed a MDIarea into the main window and have tried to load the forms created inside the main window, but it was not working. Maybe I am missing something here.
Maybe I am not used to the terminology used here, so in Qt, UI forms are widgets, controls (textboxes, labels, etc..) are widgets?
I will look around for the solution, hopefully should be able to figure it out.
Thanks. -

Well you could switch pages in stack widget with menus.However, it sounds like you a really hooked on MDI.
Note, though. they draw win 7 style on win 8/9.MDI can hold any widget, including forms.
The process is the same as inserting any other widget. -

I just have to find a good tutorial or an example for what I am looking for in QT. I guess I am having beginners trouble with Qt. Couple of examples that with the documentations are implemented in a different way which I feel will not work for me. going through them I might just land on some thing that helps me.

Hi
Can you perhaps show an image of such a desktop program you use?
Might help us pinpoint exactly what you are after.
Most app i use is not MDI in the old sense where is document is
a floating window inside the app. but more like stacked widget where I switch views.Also check out

Qt Creator for one is a MDI application.. I think there are a lot of apps which are an MDI and I have seen desktop application like the one I am trying to develop in Qt developed in c#, vb.net for windows platforms as well.
I have explained the requirement I am working on couple of times I really cannot be any more elaborate than I have been. Anyways thanks for your time. I am sure I will get to the solution.
If I get a working solution I will maybe post a sample code later on. Till then the search is on.

Yep, its a multi view application but not a MDI app in the traditional sense.
You can split a Editor view and see 2 or more at same time but the views do not have
captions and decorations.
For such design, QSplitter can be used to divide the client area into view.
You can also use QDockWidgets which also can support multiple views
and/or support floating windows.

Whatever suggestions you have suggested are pretty neat but it doesn’t really help me with my requirement.
Thank you for taking the time to post. -

Ok, then MDI area is best fit. Its 100% traditional :)
You can use any form/widget for the inner content.
just use
QMdiSubWindow *addSubWindow(QWidget *widget, Qt::WindowFlags flags = Qt::WindowFlags());
to create new window where widget is your form object.
