C# panel move with collision

由 …衆ロ難τιáo~ 提交于 2019-12-02 07:20:25
I am new to C# and Winforms and try to make a moving panel. It should move right until the end of my window and then back left. It should bounce from side to side. But the only thing happened after hours of trying is that it moves left and stops. Using this form tools: Timer = tmrMoveBox (interval: 50) Panel = pnlBox Label = lblXY (for showing the X and Y coordinates in the form) Here are my first best try: private void tmrMoveBox(object sender, EventArgs e) { if (pnlBox.Location.X <= 316) { for (int i = 0; i <= 316; i++) { pnlBox.Location = new Point( pnlBox.Location.X + 2, pnlBox.Location.Y)

问题 I am trying to create a floating panel over other pre-created panels, I tried following simple codes, but failed: var testPanel = new Ext.Panel({ id: 'testP', width: 50, height: 100, floating: true, title:'Test' }); testPanel.show(); what else I need to think about? thanks! 回答1: Following needs to be taken care of when using the floating config: 1) Fixed width - which you've done 2) The position must be set explicitly after render (e.g., myPanel.setPosition(100,100); ). You can also set the

How to make p:dashboard components draggable without panel header being set

由 梦想的初衷 提交于 2019-12-02 01:53:56
问题 As a follow up to this question. It appears the components in a p:dashboard are only draggable if their parent panel has a header set (which contains the title). How do I make it so the panels can be dragged even if the header isn't set? So the whole panel will be the handle to drag it around, not just the header.

VB / C#: Resizing two controls equally

由 流过昼夜 提交于 2019-12-01 19:14:30
I have made a window in which I will be having two groups/panels and some buttons in between them. I want to code the resizing behavior in a way that when the window expands, the two panels increase their widths while keeping the distance between them constant. Please see this mockup: As you see above, I want the 'Local' and 'Server' Panels to resize while keeping the distance in between them same. If I use anchors (Top+Left+Right+Bottom), the left panel will overlap the right one and the right's width one will go out of the window. I want them to share the increased width of the window
