Member Function Documentation

void sjgui::CWnd::Animate ( ) [inline, virtual]

Animate window and all child windows.
OnAnimate() is called, then all child windows receive this event If you override this function do not forget to call base class implementation. For example if you derive your class directly from CWnd then you should put the following line at the end of your function:
return CWnd::Animate();
Also note that you must not call this from OnAnimate() function.
See also:
OnAnimate

void sjgui::CWnd::BringOnTop ( CWnd * pWnd ) [inline]

Brings child window on top.
Brings child window to the end of the drawing list, so it would be displayed above all other child windows

bool sjgui::CWnd::CanAcceptFocus ( ) [inline]

Returns true if window can accept focus, otherwise returns false.
Window must be set to be able to accept focus, and it should be enabled and visible.

void sjgui::CWnd::Draw ( ) [inline, virtual]

Draws the window and all child windows.
This function will be called to display the contest of the window then all child windows are drawn. OnDraw() is always executed before calling draw function. If you override this function do not forget to call base class implementation of this function. For example if you derive your class directly from CWnd then you should put the following line at the end or beginning of your function:
CWnd::Draw();
Also note that you must not call this from OnDraw() function. All controls in sjgui are drawn using ortho projection and it is up to your class to change it to whatever you want, but do not forget to return it to the previous state.
See also:
OnDraw

Reimplemented in sjgui::classic::CWndCtrl, and sjgui::modern::CWndCtrl.

CRect& sjgui::CWnd::GetClAr ( ) [inline]

Client area rectangle.
Area not occupied by border or any other controls belongin to the control.

CWnd * sjgui::CWnd::GetFirstChild ( ) [inline, virtual]

Returns first child window.
Function returns pointer to the first child. Inherited classes could override this function to skip some children, that should not be accecable by other classes. Returns NULL if there is no such child. Usual ussage is:
// Get the first child CWnd* pWnd=GetFirstChild(); // if NULL is returned we are at the end while(pWnd!=NULL) { // ... do your stuf here pWnd=GetNextChild(pWnd); // go to the next child }
See also:
GetNextChild(), GetLastChild(), GetPrevChild()

CWnd* sjgui::CWnd::GetFocused ( ) [inline]

If there is no child window in focus returns NULL. There could be only one child window in focus.

CWnd * sjgui::CWnd::GetLastChild ( ) [inline, virtual]

Returns last child window.

See also:
GetFirstChild(), GetPrevChild(), GetNextChild()

CWnd * sjgui::CWnd::GetNextChild ( CWnd * pWnd ) [inline, virtual]

Returns child registred after the given one.
Function returns pointer to the next child after one passed in parameter. Inherited classes could override this function to skip some children, that should not be accecable by other classes. Returns NULL if there is no such child, or the given one was the last. I could return iterator, but if something was changed in between GetFirstChild() and GetNextChild() I would have a problem, so instead I choose some time penalty in time performances, by taking time to find a child with the given address.

void sjgui::CWnd::OnUpdatePos ( ) [inline, virtual]

Updates position of the window.
Is called from UpdatePos() function. If you draw something on the screen and do not want to recalculate absolute position of the drawn primitives you can precalculate them using this function. Window is defined by position of the upper-left corner and widht with height. Position is relative to the parent window position, so to draw anything on the screen you would need to reset viewport or add parent positon to the current position, I decided to store absolute postion of the window also, so during the drawing I have exact values, but this means that if parent changes its position child windows should update their absolute positions too. That is why this function is implemented. Note that changing size should will require call of Reshape() to take an effect.
If you want original behavior of the base class to be preserved you should call it directly. For example if you derive your class directly from CWnd then you should put the following line at the top of your function:
return CWnd::OnUpdatePos();
This function is called when you change position or size of the window.
See also:
UpdatePos

UpdatePos() is called, due to SetPos
See also:
UpdatePos, SetSize, SetPos

void sjgui::CWnd::RegisterChild ( CWnd * wnd ) [inline, virtual]

Register child window.

Attention:
Be careful calling this function when any event could occur. If called during reshaping or animation, it will invalidate iterators especially if you are using multithreading. Try to limit its usage to within constructors only! It can be overriden by parent classes to perform some additional calls or to redirect the call (example is CMDlg)

See also:
UnRegisterChild(), CMDlg

void sjgui::CWnd::Reset ( ) [inline, virtual]

If you override this function do not forget to call base class implementation of it. For example if you derive your class directly from CWnd then you should put the following line at the end of your function:
return CWnd::Reshape();
See also:
OnUpdatePos(), OnReshape()

void sjgui::CWnd::SetAllowedForFocus ( bool b = true ) [inline]

void sjgui::CWnd::SetFocusTo ( CWnd * pWnd ) [inline, protected]

Sets focus to the child window.
pWnd must be window registered with RegisterChild. OnFocusRecv() or/and OnFocusDism() could be called as a result. Use NULL to release the focus, OnFocusDism() could be called.
See also:
RegisterChild, OnFocusRecv, OnFocusDism

void sjgui::CWnd::SetHeight ( int h ) [inline]

Should be used to set the maximum window size available for drawing for right now is not used. This must be set by the function which responds to the resize event of the window.

void sjgui::CWnd::SetWidth ( int w ) [inline]

Sets width of the window.
Given value should be more then value set by SetMinSize(). Call Reshape() to apply.
