yah. now i know the STATIC control it's drawed to parent window. so using the same way of the window creation, i can create my own label ;)

that image is an animation. and the images are showed 1 above other. the correct is clean the last image and show the newone.
cambalinho 142 Practically a Posting Shark
finally i have the static control transparent:
//creating the form:
hwnd = CreateWindowEx(0, classname, strCaption.c_str(),WS_OVERLAPPEDWINDOW | WS_TABSTOP,
CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, parent, NULL, mod, this);
//sending a message for subclassing:
case WM_CTLCOLORSTATIC:
{
return DefWindowProc(HandleWindow, msg, wParam, lParam);
}
break;
//heres how i create a static control with ownerdraw style:
hwnd = CreateWindowEx(
0,
TEXT("CSTATIC"),//these must be the same of LabelClass.lpszClassName
strCaption.c_str(), WS_TABSTOP|
WS_CHILD | WS_VISIBLE | SS_NOTIFY | SS_OWNERDRAW | WS_TABSTOP,
intLeft, intTop, intWidth, intHeight,
parent,
NULL,
mod,
(LPVOID)this);
//now here the static messages for draw it:
case WM_CTLCOLORSTATIC:
{
HDC hdcStatic = (HDC) wParam;
SetTextColor(hdcStatic, RGB(0,0,0));
SetBkMode (hdcStatic, TRANSPARENT);
return (LRESULT)GetStockObject(NULL_BRUSH);
}
break;
case WM_PAINT:
{
PAINTSTRUCT ps;
BeginPaint(inst->hwnd, &ps);//inst is the static object pointer
if(inst->Paint==NULL)
{
if(inst->blnTransparent!=true)
FillRect(ps.hdc,&ps.rcPaint, CreateSolidBrush(inst->clrBackColor));
if(inst->imgtest.haveimage())
DrawHICONtoHDC(ps.hdc, inst->imgtest,1,1);
SetBkMode(ps.hdc,TRANSPARENT);
char *text=(char*)inst->strCaption.c_str();
SetTextColor(ps.hdc,inst->clrTextColor );
DrawTextEx(ps.hdc,text,-1,&ps.rcPaint,DT_LEFT,NULL);
if(inst->blnBorder==true)
DrawEdge(ps.hdc, &ps.rcPaint,BDR_SUNKENINNER | BDR_RAISEDOUTER,BF_RECT);
}
EndPaint(inst->hwnd, &ps);
}
break;
//and now heres the code for make it transparent:
void setTransparent(bool transparent)
{
blnTransparent = transparent;
LONG_PTR s;
if(transparent==true)
{
blnTransparent=true;
s=GetWindowLongPtr(hwnd,GWL_EXSTYLE);
s|=WS_EX_TRANSPARENT;
SetWindowLongPtr(hwnd,GWL_EXSTYLE,s);
}
else
{
s=GetWindowLongPtr(hwnd,GWL_EXSTYLE);
s&=~WS_EX_TRANSPARENT;
SetWindowLongPtr(hwnd,GWL_EXSTYLE,s);
blnTransparent=false;
}
InvalidateRect(hwnd,NULL,FALSE);
}
some code is from my header file. but i think that it's easy to follow.
readers: any problems please tell me.
but these label transparent have 1 problem:
(see the image)
(if i fill 1 color, that color is showed)
how can i clean the image before repaint?

even so my problem was my own function for get the letter(from button caption). i was doing several errors without notice.
heres my function:
char GettingAltKey(string text)
{
char altkey=-1;//defauld result
int textlenght=text.length()-1;
for(int i=0; i<textlenght;i++)
{
if((text[i]=='&') && (i<textlenght) && (text[i+1]!='&'))
{
altkey=upper((char)text[i+1]);
break;
}
else if((text[i]=='&') && (i>0) && (text[i-1]!='&') )
{
altkey=upper((char)text[i+1]);
break;
}
}
return altkey;
}
//button class constructor:
button(string caption="", HWND parent=WindowMain)
{
++ButtonCount;
if(caption=="")
strCaption=strCaption + to_string(ButtonCount);
else
strCaption=caption;
setParent(parent);//is where i create the button
altkey=GettingAltKey(strCaption);
if(altkey!=-1)
RegisterHotKey(hwnd,altmessage,MOD_ALT,altkey);
}
void setText(string text)
{
strCaption=text;
if(altkey!=-1)
UnregisterHotKey(hwnd,altmessage);
altkey=GettingAltKey(strCaption);
if(altkey!=-1)
RegisterHotKey(hwnd,altmessage,MOD_ALT,altkey);
InvalidateRect(hwnd,NULL,FALSE);
}
~button()
{
--ButtonCount;
if(altkey!=-1)
UnregisterHotKey(hwnd,altmessage);
DestroyCursor(hCursor);
DestroyWindow(hwnd);
hwnd = 0;
}
now works fine.
thanks for all
cambalinho 142 Practically a Posting Shark
the RegisterHotKey() is limited?
everytime that i create a button control the RegisterHotKey() id isn't the same.
//on constructor:
++ButtonCount;
altmessage=ButtonCount;
now the hotkey message:
case WM_HOTKEY:
{
if (wParam==inst->altmessage)
{
SendMessage(inst->hwnd,WM_COMMAND,BN_CLICKED,lParam);
}
}
break;
and now how i regist the hot key:
case WM_DRAWITEM:
{
DRAWITEMSTRUCT *test=(DRAWITEMSTRUCT*) lParam;
UnregisterHotKey(inst->hwnd,inst->altmessage);
RegisterHotKey(inst->hwnd,inst->altmessage,MOD_ALT,inst->altkey);
inst is the button object pointer.
the 1st button that it's created, the alt+altkey is working fine. but the 2nd button is ignored, why?
cambalinho 142 Practically a Posting Shark
thanks for all to all
cambalinho 142 Practically a Posting Shark
let me ask: why, sometimes, we use '*' and othertimes don't with 'this'?
cambalinho 142 Practically a Posting Shark
honestly that types of if's are confused to me:
if(inst->imgtest.haveimage())//same: if(inst->imgtest.haveimage()==true)
//and
if(!inst->imgtest.haveimage())//same: if(inst->imgtest.haveimage()==false)
//correct me if i'm wrong ;)
yes i use C++ 11 type with compiler... my all class's are prepared with some C++ 11 code ;)
cambalinho 142 Practically a Posting Shark
i think:
if(inst->imgtest != NULL)
more easy ;)
because test if imgtest have 1 image or not, of course that i can use haveimage() function ;)
bool haveimage()
{
if(btBitmap==NULL)
return false;
else
return true;
}
//testing
if(inst->imgtest.haveimage()==true)
cambalinho 142 Practically a Posting Shark
now it's fixed:
bool operator != ( nullptr_t ) const
{
return btBitmap != nullptr;
}
i must add these function to my class image and now works fine.
thanks to all
but continue: i have several problems with some overload operators(even reading all tutorials) :(
so what can you advice me?
cambalinho 142 Practically a Posting Shark
my objective is testing if the imgtest.btBitmap(is the image HBITMAP) have any image with != operator, just using my image object name.
cambalinho 142 Practically a Posting Shark
if i do these works fine:
if((HBITMAP)inst->imgtest!=NULL)
but i want avoid the casting...
cambalinho 142 Practically a Posting Shark
Moschops: image.... my own class. see mike post ;)
i'm failling with these operator.
inst is the control object pointer. so the important thing is the imgtest image object.
cambalinho 142 Practically a Posting Shark
i continue with errors, when i do:
if(inst->imgtest!=NULL)
i get errors:
- "ambiguous overload for 'operator!=' (operand types are 'image' and 'int')"
cambalinho 142 Practically a Posting Shark
i'm trying overload the != and == operators, but i'm getting several errors :(
bool operator==(const image &other) const
{
if(other.btBitmap==*this->btBitmap)
return true;
else
return false;
}
bool operator!=(const image &other) const
{
return !(*this == other);
}
what i'm doing wrong?
cambalinho 142 Practically a Posting Shark
sorry i don't use MFC.
i found some problems with debugging:
RECT textrect{0};
int a=DrawText (test->hDC,inst->strCaption.c_str(),-1,&textrect,DT_CALCRECT);
int intwidth=0;
int intheight=0;
if (a==0)
MessageBox(NULL,"error","erro", MB_OK);
if(textrect.bottom<inst->imgtest.height())
intheight=inst->imgtest.height();
else
intheight=textrect.bottom;
if(textrect.right>inst->imgtest.width())
intwidth=inst->imgtest.width();
else
intwidth=textrect.right;
the textrect isn't recive, sometimes, correct values.
cambalinho 142 Practically a Posting Shark
how can i do the control autosize?
i think in these way:
1 - get the text rect:
RECT textrect;
int a=DrawText (test->hDC,inst->strCaption.c_str(),-1,&textrect,DT_CALCRECT);
(the a isn't zero)
2 - testing the rectangle with image size:
if(textrect.bottom<inst->imgtest.height())
inst->intHeight=inst->imgtest.height();
if(textrect.right<inst->imgtest.width())
inst->intWidth=inst->imgtest.width();
3 - change the control size:
SetWindowPos(inst->hwnd, 0, 0, 0, inst->intWidth, inst->intHeight,
SWP_NOZORDER|SWP_NOMOVE|SWP_NOACTIVATE|SWP_NOCOPYBITS);
so why the control size isn't changed? did i forget something?
cambalinho 142 Practically a Posting Shark
anotherthing: why, from DrawThemeIcon(), i only get a black rectangle?
cambalinho 142 Practically a Posting Shark
i'm owner draw some controls.
here what i use for a button:
case WM_DRAWITEM:
{
DRAWITEMSTRUCT *test=(DRAWITEMSTRUCT*) lParam;
HIMAGELIST imlIcon=ImageList_Create(inst->imgtest.width(),inst->imgtest.height(),ILC_COLOR,1,1);
ImageList_Add(imlIcon,inst->imgtest,NULL);
HTHEME hTheme = OpenThemeData(inst->hwnd, L"BUTTON");
//fill the background with button face color
FillRect(test->hDC, &test->rcItem,(HBRUSH) GetSysColor(COLOR_BTNFACE));
if ( test->itemState & ODS_SELECTED) // If it is pressed
{
DrawEdge(test->hDC,&test->rcItem,EDGE_SUNKEN,BF_RECT); // Draw a sunken face
}
else if ( test->itemState & ODS_DISABLED)
{
DrawThemeBackground(hTheme, test->hDC, BP_PUSHBUTTON, PBS_DISABLED, &test->rcItem, 0);
}
else

DrawEdge(test->hDC, &test->rcItem,EDGE_RAISED,BF_RECT); // Draw a raised face
}
//add the transparent image to the button
if ( test->itemState & ODS_DISABLED)

SetTextColor(test->hDC,inst->clrTextColor);
SetBkMode(test->hDC,TRANSPARENT);//text background transparent
DrawText(test->hDC,inst->strCaption.c_str(),-1,&test->rcItem,DT_LEFT);
}
//draw the caption
//draw the focus rectangle
HPEN pen = CreatePen(PS_DOT,1,RGB(0,0,0));//these is the must close to the rectangle focus style
SelectObject(test->hDC,pen);
SelectObject(test->hDC,GetStockObject(NULL_BRUSH));//the rectangle will be transparent
if ( (test->itemState & ODS_FOCUS )) // If the button is focused
{
int iChange = 3;
test->rcItem.top += iChange;
test->rcItem.left += iChange;
test->rcItem.right -= iChange;
test->rcItem.bottom -= iChange;
Rectangle(test->hDC, test->rcItem.left, test->rcItem.top, test->rcItem.right, test->rcItem.bottom);
}
CloseThemeData(hTheme);
ImageList_Destroy(imlIcon);
}
break;
i see 1 problem with these 2 lines:
DrawThemeIcon(hTheme, test->hDC, BP_PUSHBUTTON, PBS_DISABLED,&test->rcItem,imlIcon,0);
DrawThemeText(hTheme, test->hDC, BP_PUSHBUTTON, PBS_DISABLED,(LPCWSTR) inst->strCaption.c_str(),-1,DT_LEFT|DT_HIDEPREFIX,0,&test->rcItem);
1 - the icon isn't drawed black and white. i only see a black rectangle with control size;
2 - the text is drawed, but why i see chinese characteres?
cambalinho 142 Practically a Posting Shark
i did a global variable that i change what form have the focus. so i change the GetFeregroundWindow() to that form, and now works fine ;)

if i uncomment that line, when the window, loses the focus, the messages aren't executed.
but the GetForegroundWindow() can give me 1 window that isn't from my application. so what you can advice me?

the szInfo is the key: if is empty the balloon isn't showed.
strcpy(NID.szInfo , "hello beaury");
if hBalloonIcon class member give us an error about not be a class member, use these line before includes files:
#define NTDDI_VERSION 0x06000000
now we can use, too, the NOTIFYICONDATA_V3_SIZE and NIF_SHOWTIP consts ;)
for use the balloon icon, the dwInfoFlags must be NIIF_USER:
NID.dwInfoFlags = NIIF_USER;
readers for use Notification messages, we must use the NIF_MESSAGE on uFlags class member.
thanks for all

i'm sorry.... i continue with problems. i don't understand how can i show the balloon :(

sorry, in these case i don't have HDC
cambalinho 142 Practically a Posting Shark
can i change the HBITMAP structure for be transparent?
because the gif's files are show me a black background color.

my message loop is wrong:
//Message Loop
WPARAM MessageLoop()
{
MSG msgEvents;
while(GetMessage(&msgEvents, NULL, 0, 0) > 0)
{
if(IsChild(GetForegroundWindow(),msgEvents.hwnd)==TRUE || GetForegroundWindow()==msgEvents.hwnd)
{
if (!IsDialogMessage(GetForegroundWindow(), &msgEvents))
{
TranslateMessage(&msgEvents);
DispatchMessage(&msgEvents);
}
}
}
return msgEvents.wParam;
}
when i change the menu style with MENUINFO structure and must do, too, for submenus:
MENUINFO mnInfo;
mnInfo.cbSize=sizeof(MENUINFO);
mnInfo.fMask=MIM_STYLE;
if(systmenu==false)
GetMenuInfo(GetMenu(MainHWND),&mnInfo);
else
GetMenuInfo(GetSystemMenu(MainHWND,false),&mnInfo);
mnInfo.cbSize=sizeof(MENUINFO);
mnInfo.fMask=MIM_STYLE | MIM_APPLYTOSUBMENUS;
mnInfo.dwStyle=MNS_NOTIFYBYPOS;
if(systmenu==false)
SetMenuInfo(GetMenu(MainHWND),&mnInfo);
else
SetMenuInfo(GetSystemMenu(MainHWND,false),&mnInfo);
now the menu commands works on menu context's.
thanks to all

my image class can read animated gif's. using a timer i can change the menu item image. but when the menu item is showed, how can i refresh it?
(i have tryied the DrawMenuBar() and SetMenu() without sucess. the image is, only, updated when i move the mouse from 1 item to another one)

i have these code for show popupmenus:
case WM_USER + 1:
{
if(lParam==WM_RBUTTONUP)
{
POINT pCursor;
GetCursorPos(&pCursor);
HMENU test=GetSubMenu(GetMenu(HandleWindow),0);
SetForegroundWindow(HandleWindow);
TrackPopupMenu(test, TPM_LEFTBUTTON | TPM_RIGHTALIGN, pCursor.x, pCursor.y, 0, HandleWindow, NULL);
PostMessage(HandleWindow, WM_NULL, 0, 0);
}
}
break;
the menu is showed normaly, but why the click message isn't working?
heres the message loop that works normaly:

{
if(IsDialogMessage(GetForegroundWindow(), &msgEvents) == TRUE)
{
TranslateMessage(&msgEvents);
DispatchMessage(&msgEvents);
}
}
}
return msgEvents.wParam;
}
the menus are using the notification style:
//for get the menu click event
//i'm using menu notifications
case WM_MENUCOMMAND:
{
MENUITEMINFO menuInfo;
menuInfo.cbSize = sizeof(MENUITEMINFO);
menuInfo.fMask=MIIM_DATA;

{
Menu *mMenu = (Menu *) menuInfo.dwItemData;
if(mMenu!=NULL)
mMenu->Click();
}
menuhandle=NULL;
}
break;
so why, when i show the menu, the click events aren't working?
strange the mouse leave\enter are working:
//when the mouse move, enter, leave and leave the menu
case WM_MENUSELECT:
{
static int Last_Menu_ID = -1;

menuInfo.cbSize = sizeof(MENUITEMINFO);
menuInfo.fMask=MIIM_DATA;

how the IsDialogMessage() can affect the Alt key?
i need use the IsDialogMessage() function for work with keyboard(when we have the child controls), but can affect the Alt key:
1 - press the Alt key: the underline, on menu(the menubar items), is showed;
2 - unpress the Alt key: the underline isn't showed.
why these behavor?
