I have an dialog with several buttons and sliders on it and am adding another button that should close the dialog and open another that is essentially a mini version it.
I need access to the buttons in the first dialog in the second mini dialog (since they should have the same functionality).
Is there a way to use the class from the first dialog on the second so that I have access to those buttons? I've tried right clicking the dialog and adding a class, but it makes me make a new one instead of being able to use an existing one.
Thanks in advance!

All I would like to do is to be able to open a new dialog from my MainWindow. I want to be able to design the dialog in Qt designer and then use the signals and slots editor to link a button press in my main window to the display of a new dialog. The dialog needs to have a couple of line edits and buttons in it and I want to avoid writing a new class in C++ every time i want a different dialog.
How can I link my main window to another dialog i created in qt designer?
You won't be able to connect the signal to startup the dialog within the designer, this will have to be in the code. But you won't need a new custom class everytime, you could easily use one class implementing different widgets.
You will have to write some c++/design some dialog everytime, since you do want to have another dialog (or at least another setup in the same dialog). You could setup the dialog to have a QStackedWidget and have an index in the constructor for having one dialog with multiple pages.
I have a design like below:
So basically, I want to embed three dialogs in the application main dialog and switch between them, for each button click i.e., button 1 will show dialog one , button 2 will hide dialog 1 and show dialog 2 .. and so on.
Each dialog will be having a different design and functions.
I tried using CPropertySheet class to Add pages but its GUI is different. It has either option for navigating the dialogs using next / back button , or from a tab control.
None of which is as per my requirement.
So I want to know is it possible to have a design like this in MFC ? If yes how? Which Class/ control should I use.
Any help will be appreciated.
What you can do is use a normal CDialog class, add your buttons to it and also create a frame/rect as a placeholder for where your embedded dialogs are to appear. The following piece of code will create and position your embedded dialog.
CRect rect;
CWnd *pHost = GetDlgItem(ID_OF_YOUR_FRAME_RECT);
pHost->GetWindowRect(&rect);
ScreenToClient(&rect);
pDialog->Create(ID_OF_YOUR_DIALOG, this);
pDialog->MoveWindow(&rect);
pDialog->ShowWindow(SW_SHOW);
On button clicks, you hide the previously shown dialog (SW_HIDE) and show your selected dialog(SW_SHOW) with ShowWindow(...).
If you create your embedded dialogs with IDD_FORMVIEW style in the add resource editor it'll have the proper styles for embedding.
Another option is probably to use an embedded PropertySheet and hide the tab row and programatically change the tabs on the button clicks. I just find it to be too much fuzz with borders, positioning, validation and such for my liking.
If you have the MFC Feature Pack, that first came with VS2008 SP1 and is in all later versions, you might like to consider CMFCPropertySheet. There are a number of examples on the linked page, that are very similar to your design.
For example, this:
What worked for me just using dialog based application is SetParent() method. Dont know why nobody mentioned it. It seems to work fine.
I am doing like below:
VERIFY(pDlg1.Create(PanelDlg::IDD, this));
VERIFY(pDlg2.Create(PanelDlg2::IDD, this));
VERIFY(pDlg3.Create(PanelDlg2::IDD, this));
::SetParent(pDlg1.GetSafeHwnd(), this->m_hWnd);
::SetParent(pDlg2.GetSafeHwnd(), this->m_hWnd);
::SetParent(pDlg3.GetSafeHwnd(), this->m_hWnd);
Now I can show or hide a child dialog at will (button clicks) as below:
pDlg1.ShowWindow(SW_SHOW);
pDlg2.ShowWindow(SW_HIDE);
pDlg3.ShowWindow(SW_HIDE);
I have a document within MFC C++ application. I need to delete one the buttons from the particular CMFCToolbar within a code (not resources) completely, even preventing a user to restore the button via toolbar customization dialog. At this moment I use RemoveButton method of CMFCToolbar but it only makes the button invisible and it can be restored via toolbar customization dialog that is not an option for me at this time. I will be very glad if you suggest something that can help me there.
There are two internal lists in CMFCToolBar that are used to reset the Buttons upon customization.
They are named m_OrigButtons and m_OrigResetButtons.
You may need to derive your own class and delete the buttons with the specific IDs from there.
But better: Never to include such a button on the first time when the toolbar is created!
I have tons of existing code using wxWidgets. The main window is wxDialog. Now I have to add a wxMenuBar to that dialog. But, in order to do it, the window should be derived from wxFrame.
Is it possible to add a wxMenuBar to the wxDialog?
If not, is it possible to convert existing code in a way that main window is derived from wxFrame instead from wxDialog?
It's not possible to add a native menu bar to a wxDialog, however, it is possible to use a non-native menu bar control like wxFlatMenuBar (not included with wxWidgets), and add it to the top of the dialog as if it was just another control. Also note though that besides being a non-native menu bar, you also won't be able to use some wxWidgets API to manage it like wxUpdateUIEvents.
There's at least a couple things you will need to take into consideration when changing a wxDialog to a wxFrame.
First, if your dialog is a modal dialog, you will need to manually set the new frame as modal (using wxWindow::MakeModal()) rather than calling ShowModal().
Second, if you had any event handlers setup for the affirmative (OK/Apply button for example) or escape (Cancel or window close) events, you will likely need to rewrite them to handle changes in window behavior.
I have a hard time hiding a modal dialog box. What I am doing is - I am trying to design a UI for my own application in MFC, kind of a setup assistant.
In the 1st dialog box I have NEXT button, so when I click that it has to hide the 1st dialog box and move on to the 2nd dialog box, where I have some controls in 2nd dialog box.
How can I achieve that?
I have never tried to hide a Modal dialog...not sure how it can be done.
Anyway, it seems to me you don't need to hide the dialog but destroy the first one and create the second one. You can use EndDialog to terminate a modal dialog.
But MFC has its own mechanism to create your own wizard, have a look at this class CPropertySheet. I am sure you can find thousand of examples, this is one.
Hope it helps.
You can use ShowWindow() function to hide modal
Its default patametet is SW_SHOW which is equal true value 1 and
To hide modal use SW_HIDE value when you click next button
You just use ShowWindow(SW_HIDE) If you make prev button you should use modal pointer
Or next modal should child modal because you cannot have prev modal variable.
I wish you understand me for my english
