SplitterWindow change message? [modified]

1-Feb-10 11:03

Kind of. COM uses window messages to communicate. When you hold down the X button, the UI thread enters a modal message loop and won't process COM related windows messages. Maybe have the event handler on a different thread in the client?

Hi there,
I've written a WTL SDI application, that uses splitter windows. I'd like to know how what messages to listen for to pick up when the splitter windows are moved.

I've tried listening to WM_SIZE, but only the CMainFrame seems to send WM_SIZE messages.

Here's my CSplitterImpl derived class:

template <bool t_bVertical = true>
class CViewSplitterT : public CSplitterWindowImpl<CViewSplitterT<t_bVertical>, t_bVertical>
{
public:
    DECLARE_WND_CLASS_EX(_T("Splitter"), 0, -1)	

	CViewSplitterT(){ }
};

typedef CViewSplitterT<false>   CHorSplitter;
typedef CViewSplitterT<true>	CVertSplitter;

What should I be listening for in the message map of my CMainFrame?

All suggestions welcomed!

When you don't know what messages are being sent, I'd suggest using Spy++ (distributed with Visual Studio) to look at what messages are flying around.

Using that method on a WTL app with splitter that I have, I don't think the main frame gets any notification of splitter position change. The only thing I can see is the views inside the splitter getting WM_WINDOWPOSCHANGING and WM_WINDOWPOSCHANGED messages when they are resized.

ATL ActiveX control embedded in Internet Explorer not receiving WM_CREATE, WM_DESTROY, WM_SHOWWINDOW messages.
Other messages (WM_LBUTTONDOWN for example) are successfully handled.
The same control embedded in the test application works fine (all messages are received).

Thanks in advance

Problem in transform function

ashtwin16-Dec-09 1:50

Hi, i am using transform function to transform a vector to a map but getting the following error.

multiMapType.obj : error LNK2001: unresolved external symbol "struct std::pair<enum PC::PC_type,class PC> __cdecl std::make_pair(enum PC::PC_type const &,class PC const &)" (?make_pair@std@@YA?AU?$pair@W4PC_type@PC@@V2@@1@ABW4PC_type@PC@@ABV4@@Z)
Debug/MultiMapType.exe : fatal error LNK1120: 1 unresolved externals

The code snippet is as follows

int main( )
{
	const PC::PC_type kind[] = { PC::IBM,PC::IBM, PC::Dell, PC::HP,PC::HP, PC::HP };
	
	const int num_appliances = 3;
	
	vector<PC> v;
	for( int i = 0; i < num_appliances; ++i )
		v.push_back( PC( kind[i], i, i ) );
	
	
	// work with a multimap. key is appliance type, value is PC
	typedef multimap<PC::PC_type,PC> PC_multimap_type;
	
	PC_multimap_type stock;
	const PC desired( PC::HP );
	
	// load the appliances into the multimap
	transform( kind, kind+num_appliances, v.begin(),inserter( stock, stock.end() ),make_pair<PC::PC_type,PC> );	
        PC_multimap_type::const_iterator stock_end = stock.end();
	
	// search for first occurrence of key
	PC_multimap_type::const_iterator spot = stock.find( desired.appliance() );
	
	if( spot != stock_end )
		spot->second.print();
	else
		cout << "Don't have a " << desired.name() << " in stock\n";
	return 0;
}

Please help.

Thanks

Given that I've made assumptions about context (definitions of PC? PC_type? headers you include?), it's difficult to say if I've done the same as you.

But your code compiles and links for me under VS2008. What version are you using?

Hi,
Thanks for replying. I am using VS98(VC6.0) Smile | :)

.

The headers file and defination of PC is as follows

#include <algorithm>

#include <functional>

#include <iomanip>

#include <iostream>

#include <map>

#include <string>

#include <utility>

#include <vector>

 

using namespace std;

 

class PC

{

public:

            enum PC_type { Dell, HP, IBM, Compaq };

            

            PC( PC_type appliance = Dell, int model = 220,

                        int serial = 0 );

            

            bool operator<( const PC& rhs ) const;

            

            PC_type appliance() const;

            int model() const;

            string name() const;

            

            void print() const;

            

            int serial() const;

            

private:

            PC_type appliance_;

            int model_;

            int serial_;

            

};

My commiserations - VC6 sucks for template usage.

Anyway - try declaring the make_pair instance you need before main():

template std::pair<PC::PC_type,PC> std::make_pair<PC::PC_type,PC>(PC::PC_type,PC);

int main( )
{
   // Rest of your code

Hi, i tried the declaration before main

template std::pair&lt;PC::PC_type,PC&gt; std::make_pair&lt;PC::PC_type,PC&gt;(PC::PC_type,PC);
int main( ){

but still getting the same error.
May be some problem in project settings.

Stuart Dootson17-Dec-09 0:26

No, shouldn't be project settings. And I don't have VC6 to test with. Oh well.

The program is getting build properly if i use a function insted of make_pair in the last parameter of the function transform and return a pair from that function.

pair<PC::PC_type, PC> MyFunction(PC::PC_type pcType, PC pc)
{
  return make_pair(pcType, pc);
}
transform( kind, kind+num_appliances, v.begin(),inserter( stock, stock.end() ),MyFunction);

Stuart Dootson17-Dec-09 21:36

17-Dec-09 21:36

Yes...I should have mentioned that solution Blush | :O

In this one, you're not asking the compiler to automatically instantiate a function from the reference in transform, so yes, it includes all the necessary code.

Does it mean that whatever i was doing earlier was not correct.

Stuart Dootson18-Dec-09 1:57

18-Dec-09 1:57

Ummm - it should have been correct and OK - but VC6 is a bit rubbish, which is why it didn't work.
