[Qt-qml] 答复: 答复: 答复: 答复: how to draw line in QML

[宫长辉]

I’d read this example too.

Only a blank dialog was displayed because of no “CustomComponents”.

Could you tell me where I can get it ?

 

Regards.

Hi,

 

A while back I also needed a line in one of my QML applications. I used the
code from this example
http://www.developer.nokia.com/Community/Wiki/CS001627_-_Creating_a_custom_Q
ML_element_with_Qt

I need to draw a wave composed by 1000 continuous lines.

And mostly 8 waves were needed in one graph.

Even the product should be run in ARM.

 

So I’m afraid that it will cost too much CPU and memory, If I implement it
with rectangle,

 

Regards.

Anyway for the lines, you can use the rectangle and some math to calc the
angle and coords if the line is not horizontal or vertical.
