How can I change the application icon on mouseover? I want to put some menu items in the system menu of my CDialog, and I want the icon to highlight when the user mouses over it to indicate that it is a user interface component (similar to how recent versions of firefox have the firefox menu in orange and when you mouseover it, it highlights).
UPDATE
By "application icon" I mean the system menu icon. Also I just came across the CMFCRibbonApplicationButton class which, while not the system menu, also looks promising.
Check WM_NCHITTEST for HTSYSMENU code and then call SetIcon.
There is the code to implement MouseOverEvent: http://www.codeproject.com/KB/cpp/mouseenterleave.aspx When you catch the event you can do whatever you like.

Are notification/alert windows (that appear above the Windows System Tray) like the examples below just a standard window, owner drawn HMENU's or are they implemented using NOTIFYICONDATA? Note: I know that the actual system tray icon is implemented using NOTIFYICONDATA, but are the notification windows also implemented using this structure?
In my WinAPI C++ application I want to show a similar notification where it will appear above the system tray icon, have buttons, horizontal scroll bars and etc. I know I can just create a new HWND, position it above the system tray and show that but if there is a specific WinAPI 'System Tray Notification' class/function I would prefer to use that, thus my question.
Are notification/alert windows (that appear above the Windows System Tray) like the examples below just a standard window, owner drawn HMENU's or are they implemented using NOTIFYICONDATA?
These are custom dialogs displayed when needed. They are not implemented using NOTIFYICONDATA. You can use Shell_NotifyIconGetRect() to get the current location of your tray icon when needed.
Tray notifications are all about notifying the process that owns the icon that a click event has occurred so it can then do its thing, whatever that may be.
There is no specialised mechanism or framework for anything GUI related in this case.
Best Practices: When a user right-clicks the icon, it should
bring up a normal shortcut menu. However, the result of a single
click with the left mouse button will vary with the function of the
icon. It should display what the user would expect to see in the form
best suited to that content—a popup window, a dialog box or the program
window itself. For instance, it could show status text for a status icon,
or a slider for the volume control.
I have an application in which users, upon logging in, are prompted with a modal dialog where they must choose the facility they wish to work out of. At this stage, the application looks like this:
The modal dialog is shown by calling this method:
bool __fastcall ShowFacChoiceForm()
{
TFacChoiceForm *Form = new TFacChoiceForm( Application );
bool Result = ( Form->ShowModal() == mrOk );
delete Form;
return Result;
}
In this case, TFacChoiceForm inherits from TForm so the ShowFacChoiceForm() function is calling the standard TForm.ShowModal method documented here.
The issue I am running into is that if my application loses focus, it cannot become the active window again unless the modal dialog itself is clicked. To better illustrate this, I will present the following scenario:
Lets say its Friday afternoon and I decide to goof off a bit and read some web comics. With my application open, I open up another window on top of it, like so:
Then, out of nowhere my boss comes in for a performance review, and I attempt to refocus my application by clicking somewhere on the main form. For example, at the position of this red X in the next image.
In the above image, I have clicked at the location of the red X. Now, both the form containing the web comic, and my application are inactive. Thus, my application does not come to the front of the screen.
However, if I am able to click somewhere on the modal dialog, like the red X in the following image...
...then my application comes to the front like one would expect.
To solve this, I have looked at using something like SetForegroundWindow from the Windows API, but I have not been able to find a way to trigger the event, since my main form does not fire events while I have a modal dialog open.
My question is, how can I make sure that if the user clicks anywhere on my application that it is brought to the front? Is there a property I can edit in my form to do this?
If you set modalresult to mrcancel in the ondeactivate of the modal dialog then the main form will get focus when its clicked. You can then check if the user is logged in the mousedown event of the main form and if not, show the modal dialog again.
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);
Does anyone know if it is possible to change the icons on the MFC VSListBox Dialog Control?
Specifically I'm trying to change the folder icon to a '+' icon instead:
I haven't tried it myself, but CVSListBoxBase::AddButton() seems to be what you need.
CVSListBox derives from CVSListBoxBase, and when you call CVSListBoxBase::SetStandardButtons to set the buttons, it calls AddButton() for each button.
The documentation for CVSListBoxBase is unfinished, so you'll have to "play" with it, but you can read the code in afxvslistbox.cpp/.h
I would like to add a simple text button to my c++ win32 application. I'm creating the button using CreateWindowEx function, but can't figure out the correct style to do so. I would like to display a text only button and be able to recive messages when the user clicks on it. The style i would like to get is identical to the text button in windows 7 system volume control (where it says "Mixer"). If possible i would like to display a tooltip also.
That mixer control looks more like a hyperlink control than a button. I'd go for the SysLink control if that's what you need.
You could create a "Button" class window with the BS_OWNERDRAW style and handle the WM_DRAWITEM messages. In your WM_DRAWITEM message handler you can simply display the text.
Actually that button is an owner draw button - it listens to mouse move messages and when you hover over it, it underlines the text (the syslink control doesn't have this behavior). Otherwise it's a stock button.
