Hi: I want to scale the frame size to fit different window size. In my way , I used layoutWidth() to get the displaying size and used contentsWidth() to get the web contents truly size, but both of this values sometims are same. For example, I launch GtkLauncher to browse google, I got the correct layoutWidth and contentsWidth value at the first time. Ater then, I click on the url entry and press enter key, the page will be reloaded, but this two function will return a same value. Is it right? I'm curious about what meaning of these three functions: 1. visibleWidth() 2. layoutWidth() 3. contentsWidth() I think layoutWidth() just the visiable area width of whole window, it isn't including title, toolbar, scrollbar, border, and other things, and I think contentsWidth() is the width of web page contents. If this is right, I have a weird case. I make the window size of GtkLauncher is 480x272, but the layoutWidth() will return 510 when I browse google. It looks like not the true visiable area width. Besides, the visableWidth() is the same as layoutWidth(). If I want to get the width and height of visiable area and web page contents, does any function I can use? Thanks in advances, Graffine
