The problem is that each time to load a .layout file you attempt to recreate windows with the same name; each window name must be unique.
Here's some
imaginary code (
it will NOT compile):
Code: Select all
CEGUI::Window* cloneLayoutContents(const CEGUI::String& layoutFile, const CEGUI::uint& id = 0)
{
/* Clones the window hierarchy contained within a .layout file
* Format specifiers:
* 0 forced digit: will be replaced by a digit or if here is no digit, by a zero
* # potential digit: will be replaced by a digit if there is one otherwise nothing
* ' literal character: the following character is to be treated as a character
* rather than a format specifier
*
* The following hierarchy is assumed:
* ParentName000/
* child1Name
* subChild01Name
* subChild02Name
* child2Name
*
* After this function is called the following hierarchy will be present:
* ParentName001/
* ParentName001/child1Name
* ParentName001/subChild01Name
* ParentName001/subChild02Name
* ParentName001/child2Name
*/
using namespace CEGUI;
String namePrefix;
Window* clone = readLayout(layoutFile);
String mask = clone->getName(); // The top-level window contains the mask for the lower level windows
uint newID = id;
while(true)
{
if(!ICU::formatText(String(newID), mask, "0", namePrefix))
return 0; // Error formatting the window prefix
if(!existsWindow(namePrefix))
break;
++newID;
}
clone->setName(windowPrefix);
renameClonedWindows(clone, windowPrefix);
return clone;
}
void renameClonedWindows(const CEGUI::Window* parent, const CEGUI::String& namePrefix)
{
// Rename each child window by prefixing it with the top parent's name using namespace CEGUI;
for(Window* child = parent->getFirstChild(), child, child = parent->getNextChild())
{
child->setName(namePrefix + child->getName());
renameClonedWidgets(child, namePrefix);
}
}
ICU::formatText is coming from the Wiki entry called Formatted Numbers/Text.
My idea/concept is that the layout defines window names with zeros (000). The cloneLayoutContents() function loads the .layout file, creates all the 000 windows and subwindows, and then renames/increments them to 001. If you call this function a second time it would recreate the 000 version and then increment it to 002.
If you do go along and code this imaginary function please Wiki it.
i found it by a lucky hazard it's the
