由 限于喜欢 提交于 2019-12-12 17:07:44
问题 I have a map application and a submenu which has dynamically added objects (i.e. points on a map) added to the submenu, depending on the layer that is loaded. I have the ability to hide each individual objects (i.e. a point) by clicking on the corresponding submenu item. Is there any way to organize the submenu? When there are a lot of points (i.e. 100) the entire submenu takes up the screen. Can I add a scrollbar to a submenu? I looked in the documentation, but couldn't find anything that

Scrolling panel using horizontal scroll bar

问题 How can I apply a horizontal scroll bar to a Panel? I'm working on 2d tiled map editor and I'm using a Panel to hold the contents. When my map is bigger than my panel it just goes off and becomes invisible, would it be possible to apply custom scroll bars? 回答1: The Panel is derived from ScrollableControl. So there is a property AutoScroll. Just set it to true and the rest will be done automagically. 回答2: While this no longer applies as the question has been clarified to target winforms, in

问题 I have a bug after loading my seek bars. The thumb doesn't match with the progress value. After clicking the first time on the progress bar, the thumb moves correctly. Is there any solution for this problem? Thanks for help! Screenshot: 回答1: Check that your thumb offset in not set android:thumbOffset="-10dp" 回答2: You haven't provided much in the way of detail. I've found with Android 2.3 and earlier that if I modify the thumb within my code I then need the following sequence: int progress =

由 只谈情不闲聊 提交于 2019-12-12 13:31:31
问题 By default, the Horizontal ScrollBar of a HorizontalList component will be at the bottom. Is there a way to reposition it so it is at the top? Just for clarity, I do not mean moving the scroll position using either scrollToIndex or horizontalScrollPosition or similar, but the actual physical position of the scrollbar component. Any suggestions would be very appreciated! 回答1: I was looking for something similar myself a while ago and found this post. I eventually ended up solving my problem in

jQuery datepicker causes page overflow

由 一世执手 提交于 2019-12-12 12:28:29
问题 I am using the datepicker control from jQuery-ui 1.8. from-date is a text input. I am attaching a very simple datepicker: $('#from-date').datepicker(); This causes the page to overflow (vertical scrollbar), which I am trying to avoid. As soon as I click the from-date, the datepicker control appears, and the scrollbar dissapears. After dismissing the datepicker, the scrollbar doesn't appear anymore. The text field is inside a div that has overflow:auto and a fixed height and width. I suspect
