Fit the size to the parent for QQuickItem C++ Object
-
My environment is Qt 5.4 desktop MSVC2013 and QtQuick 2.4 on Windows 8.1 64bit.
I want to fill the custom qml object extended by QQuickItem on the parent and I wrote the code like this.
//QQuickItem *item; item->setParentItem(parentItem); (*case 1) item->setProperty("anchors.fill", "parent"); (*case 2) item->setProperty("width", "parent.width"); item->setProperty("height", "parent.height");
But, those didn't work. If these ways cannot be used, is there any way alternative to implementing it only by C++?

Hi @Tank2005,
AFAIK settinganchors
wont work from C++ side. You have to either do it on QML side or you can calculate thex
andy
positions programmatically on C++ side and set them. The latter can be done following way:child->setProperty("x",parentItem->width()/2-child->width()/2); //calculate and set child->setProperty("y",parentItem->height()/2-child->height()/2);
Edit: Since you want to fill you can use
parentItem
'swidth
andheight
item->setProperty("width", parentItem.width); item->setProperty("height", parentItem.height);
