popup

问题 I have a .Net application that dynamically creates a small HTML page and pops it up in a new window using the javascript document.open method. Everything with that functionality is working fine. Now I want to add a button to the HTML page that prints the page.

问题 I've went to this tutorial to do a modal pop up window, and it seems pretty nice for what I need to do. However, I was wondering if someone can help me figure out what I need to calculate to change the dialog box so it'll follow whenever you resize the browser.

问题 I need to add a popup menu to the JFrame , but when I drop that component there it just dissappears. I can see it in code, but there is no way to edit anything about it. Is there a way I can edit it like say menu bar ? I use Netbeans 7.2.1 if that is important.

问题 I have added a label as an image(icon) to a widget in Qt. I want to display a pop-up menu when the user clicks (left or right click) on the label. How can I achieve this ?
