How to draw grid using swing class Java and detect mouse position when click and drag

无人久伴 提交于 2019-11-27 07:09:06
I am trying to create a grid UI (5*5) using Swing classes. I tried a nested loop and adding a jPanel dynamically to the jFrame. And I also tried to change the background colour of each jPanel when user clicks and drops over it. But with my code there are huge gaps between each cell and I can't get the drag event to work. public class clsCanvasPanel extends JPanel { private static final int intRows = 5; private static final int intCols = 5; private List<JPanel> jpllist = new ArrayList<JPanel>(); public clsCanvasPanel() { /* * * Add eventListener to individual JPanel within CanvasPanel * * *

Raphael JS : how to remove events?

泄露秘密 提交于 2019-11-27 06:57:56
问题 I use the Raphael .mouseover() and .mouseout() events to highlight some elements in my SVG. This works fine, but after I click on an element, I want it to stop highlighting. In the Raphael documentation I found : To unbind events use the same method names with “un” prefix, i.e. element.unclick(f); but I can't get this to work and I also don't understand the 'f' parameter. This doesn't work , but what does?? obj.click( function() { this.unmouseover(); }); 回答1: Ok, what you have to do is pass

Mouseover to select item in listbox in WPF

*爱你&永不变心* 提交于 2019-11-27 06:55:10
问题 I am relatively new to WPF, but I would like to know how can I enable a listbox to select an item based on a mouseover event instead of the button click. I would like the item to be selected when the mouse is over the selected item, without having to press click first. Thank you 回答1: You may write a simple ListBoxItem Style with a Trigger on the IsMouseOver property that sets the IsSelected property: <ListBox> <ListBox.ItemContainerStyle> <Style TargetType="ListBoxItem"> <Style.Triggers>

How to show hidden divs on mouseover?

问题 How to show a set of hidden div's onmouseover? For example : <div id="div1">Div 1 Content</div> <div id="div2">Div 2 Content</div> <div id="div3">Div 3 Content</div> All div's need to be shown onmouseover event. 回答1: If the divs are hidden, they will never trigger the mouseover event. You will have to listen to the event of some other unhidden element. You can consider wrapping your hidden divs into container divs that remain visible, and then act on the mouseover event of these containers.

How to remove default mouse-over effect on WPF buttons?

 ̄綄美尐妖づ 提交于 2019-11-26 19:54:55
My problem is that in WPF, whenever I try and change the colour of a button's background using triggers or animations, the default mouseover effect (of being grey with that orange glow) seems to take priority. After extensive searches I'm clueless as to how to remove this effect. You need to create your own custom button template to have full control over the appearance in all states. Here's a tutorial . dodgy_coder This is similar to the solution referred by Mark Heath but with not as much code to just create a very basic button, without the built-in mouse over animation effect. It preserves

iPad/iPhone hover problem causes the user to double click a link

旧城冷巷雨未停 提交于 2019-11-26 19:14:56
I have some websites I built times ago, that use jquery mouse events...I just got an ipad and i noticed that all the mouse over events are translated in clicks...so for instance i have to do two clicks instead of one..(the first hover, than the actual click) is there a workaround ready to solve this? maybe a jquery command i shoudl have used instead of mouseover/out etc.. thanks! Haven't tested this fully but since iOS fires touch events, this could work, assuming you are in a jQuery setting. $('a').on('click touchend', function(e) { var el = $(this); var link = el.attr('href'); window
