Have you tried WM_MOUSELEAVE which is in Win98-> ?

Subject: [GD-Windows] Detecting mouse exiting window?


Is there a clean way of detecting when the mouse cursor has exited my
window?  WM_MOUSEMOVE and WM_NCMOUSEMOVE messages stop coming in the
moment the mouse exits the window.  The only other thing I can think of
is to actually poll the mouse position and see if it's in my client area
(blech).

[Brian H. <bri...@py...>]

Er, no, especially since it's nowhere in my help docs =(

And, unfortunately, I need to run on Win95 still (yeah yeah yeah...).

I "fixed" the problem by sitting in my WM_TIMER and calling
GetCursorPos() and generating application mouse moved events if the
mouse it outside the window.  *puke*  But it works. =)

Thanks,

You can Capture the Mouse-Cursor.
Than you will get all Mouse-Move-Messages and you can check if the Mouse-Pos
is still in your Window.

I strongly advise against this. It will hurt you later with usability
problems when the user wonders why his mouse doesn't seem to work properly.

RE: [GD-Windows] dll export and template

[Nicolas R. <nic...@fr...>]

Yes... template and DLLs are badly working together...

Under VC7 you can at least declare the template exported...
template<class T> class __declspec(dllexport) mytemplate
{
};
will correctly export the template.


Note however that the export is only done on used template definitions... Export/import
scheme defined automatically by VC++ is not sufficient...
Let say you have a header containing:
template<class T> class MYDLL_API mytemplate
{
};

A DLL is compiling with MYDLL_API to __declspec(dllexport). If it use it with T =
MyDLLClass1 and MyDLLClass2, only mytemplate<DLLClass1> and mytemplate<DLLClass2> will be
exported.

If an external program is including the header (with MYDLL_API to __declspec(dllimport))
it won't be able to use the template for a "ExeClass" since it won't be exported by any
DLL...


Still havent find any way to correctly export the template itself (but using the #pragma
warning(disable:xxxx) before using a non exported template).


Nicolas.

There was a compile warning when I  use template in my export class of DLL.  And the
compiler
will give an error if I put __declspec(dllexport) keyword before the my template
definition.
My question is whether it is safe if I just disable the warning.

The warning is:
"The specified base class was not declared with the __declspec(dllexport) keyword.A base
class or structure must be declared with the __declspec(dllexport) keyword if a function
in a derived class is to be exported. "
.
The code is:
template<class T> mytemplate
{
    T t;
public:
    void SetData( T &_t ){ t = _t; }
};

class MYDLL_API MyClass
{
    mytemplate<int> data;

public:
    ....
};

Could you explain your Problem with this approach a little bit more precise
?

RE: [GD-Windows] Detecting mouse exiting window?

[Brian S. <bs...@mi...>]

If your app captures the mouse all the time, it makes it pretty hard for
the user to click on other windows...

Capturing the mouse seems most useful for processing things like custom
buttons and drag-and-drop behaviors, where you need to get mouse down
messages and mouse up messages in pairs.  When they mouse down, you
capture the mouse; when they mouse up, you release it.

RE: [GD-Windows] Detecting mouse exiting window?

[Nicolas R. <nic...@fr...>]

I guess the idea is:

1. To capture the mouse on first WM_MOUSEMOVE received by window (mouse enters)
2. To get each single mouse move message afterward.. Test if its outside of window..
    If inside => 2
    If outside => 3
3. Release mouse capture => 1

If you want to go ahead with that scheme, good luck... Remember:

 - Handle the WM_CAPTURECHANGED message
 - Check against the client rect so the the window controls (minimize, etc)
work.
 - Release the mouse whenever the window (NOT the app - might be a child
window) loses focus.
 - Make sure that all windows special keys work properly while the mouse is
captured - not sure if mouse capture affects that.
 - Whenever in doubt, Release the mouse - if it's on the window you'll
recapture it when it moves again.
 - Many other things I'm sure will go wrong.

The polling solution may be a hack but at least it's a compliant way to
overcome a limitation of Win95.
