Detailed Description

Simplify maintenance of icons with this stack of IconNode objects.

This is essentially a Laxkit::RefStackPtr<IconNode> with some helper functions to ease lookup of icons as button boxes come and go. The stack is sorted by id.

Todo:

Eventually, it might be in charge of generating pixmap icons from an icons.svg or icons.laidout or something of the kind.

Constructor & Destructor Documentation

Laxkit::IconManager::IconManager

(

)

Icons are added only when needed by GetIcon(), which uses findicon().

Member Function Documentation

void Laxkit::IconManager::addpath

(

const char *

newpath

)

Add path to index 0 position of the path stack.

When passed a name that is unrecognized, then the all the icon paths are searched for a loadable image named name.png.

References newstr(), and Laxkit::PtrStack< T >::push().

LaxImage * Laxkit::IconManager::findicon ( const char *  name )

protected

Search for a icon file "name.png" in all the icon paths.

Install and return the icon if found, else NULL.

This function assumes that name is not already in the stack.

References appendstr(), Laxkit::PtrStack< T >::e, Laxkit::anObject::inc_count(), InstallIcon(), Laxkit::load_image, Laxkit::PtrStack< T >::n, and newstr().

Referenced by GetIcon().

Laxkit::LaxImage * Laxkit::IconManager::GetIcon

(

const char *

name

)

Returns the icon. The icon's count is incremented.

If name does not exist, then the icon is searched for in the icon paths, and the first one found is installed.

References findicon().

int Laxkit::IconManager::InstallIcon	(	const char *	nname,
		int	nid,
		Laxkit::LaxImage *	img
	)

If nid<=0, then make the id one more than the maximum nid in stack.

Todo:

*** must check that the icon is not already installed
