Hide a swing component without revalidating the layout?

由 跟風遠走 提交于 2019-12-20 05:15:27
问题 If I set up a JFrame with some components and a layout manager, which initially looks perfectly fine, and then later due to some condition (say, clicking a button) I hide one of those components - the layout manager shuffles all the components around again. See example code - initially 3 buttons appear. When you click the Hide button, the Hide button is hidden - but the two outer buttons then squash together. When you click the show button, they move apart again to make space. How can I stop

问题 I have a C# application with 2 simultaneous visible forms, and I need to hide mouse cursor when it is over only on one of them. If I use Cursor.Hide() it applies the change for both of them. 回答1: You can make a "blank" cursor, and set myForm.Cursor = blankCursor; This will make that specific form show a specific cursor, which could be completely transparent. 回答2: You need to implement this logic by using the MouseEnter and MouseLeave events one each form something like: private void frm1

由 天大地大妈咪最大 提交于 2019-12-20 03:05:17
问题 The below code allows a div to appear when the user rolls over a link. The issue is, is that the div doesn't disappear when the user rolls off the link. Is there anyway we can make it so that when the user rolls of the link the div disappears, but the user is still able to bring their cursor down and interact with items in the div..... any help would be appreciated. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html

How to make a div disappear on hover without it flickering when the mouse moves?

由 久未见 提交于 2019-12-19 15:59:13
问题 I've seen answers suggesting just display:none on the :hover css. But that makes the div flicker when the mouse is moving. EDIT: Added jsfiddle 回答1: display:none will take the element out of the render tree, so it loses :hover state immediately, then reappears and gets :hover again, disappears, reappears, etc... What you need is: #elem { opacity:0; filter:alpha(opacity=0); } It will leave the place empty, so no flickering will appear. (Demo or yours updated) 回答2: Optionally with CSS3, but
