Detailed Description

A clickable button.

When the user clicks a GButton the OnNotify() event of the GetNotify() or GetParent() view will be called with this control as the parameter. Allowing action to be taken in response to the click. This event by default bubbles up to the top level window unless some other view intercepts it on the way up the chain of parent views.

int  x,
int  y,
int  cx,

Member Function Documentation

bool GButton::Name char *  n  ) 
 

Sets the utf-8 text associated with this view.

Name and NameW are interchangable. Using them in any order will convert the text between utf-8 and wide to satify any requirement. Generally once the opposing version of the string is required both the utf-8 and wide copies of the string remain cached in RAM until the Name is changed.

Reimplemented from GView.

char16* GButton::NameW  )  [inline, virtual]
 

Returns the wide char text associated with this view.

On Win32 the wide characters are 16 bits, on unix systems they are 32-bit characters.

Reimplemented from GView.

void GButton::SetFont GFont Fnt,
bool  OwnIt = false
[virtual]
 

Sets the font for this control.

The lifetime of the font passed in is the responsibility of the caller. The GView object assumes the pointer will be valid at all times.

Reimplemented from GView.
