panel

In C# i want to create a panel that has the properties of a MDI container ie. isMdiContainer = true. I tried something like this form.MDIParent = this.panel1; But that dont work. Any suggestions? You could create custom form, remove all borders, and toolbars to make it look as closely to a panel as possible. Then make that new custom form a MdiContainer. Basically, you can only set the IsMDIContainer property on a Form. This means that only a form can be a MdiContainer. It is possible to create an MDI-panel and show forms in that panel, something like the code below will do the job Mdi-Panel

I have a panel on my form with AutoScroll set to true so a scrollbar appears automatically. How can I make it so a user can use his mouse wheel to scroll the panel? Thanks SO. The panel or a control in the panel must have focus. Note that if the control with focus has scroll bars, it will scroll instead of the panel. What worked for me was adding panel1_MouseEnter EventHandler: private void panel1_MouseEnter(object sender, EventArgs e) { panel1.Focus(); } Below code works for me..... Public Form { InitializeComponent(); this.MouseWheel += new MouseEventHandler(Panel1_MouseWheel); } private

Normally I know how to start off, have a few tutorials or even experience, but at this point I don't even know how to call it. Perhaps just by telling me how to correctly define this could be a solution to my problem (-> based upon name, I can correctly search). Let's give you this quick mockup I just made. I'm looking for 1: how do you call this, but especially 2: How would I create such? I would like to create panels, a few stacked above eachother and with the click of the 'next' button on each panel, you can move that panel to the left (or right (backwards)) to go the next tile. Let's say

I'm new to Flutter so i am trying to get into it. But I'm hanging on creating an ExpansionPanelList with ExpansionPanels in it. And Like the title says all created in googles Flutter. My code so far: import 'package:flutter/material.dart'; class ShoppingBasket extends StatefulWidget { @override ShoppingBasketState createState() => new ShoppingBasketState(); } class ShoppingBasketState extends State<ShoppingBasket> { @override Widget build(BuildContext context) { return new ExpansionPanelList( children: <ExpansionPanel>[ new ExpansionPanel( headerBuilder: _headerBuilder, body: new Container(

I'm implementing an application which want to draw lines in the panel. But the panel must be auto scrolled as it size can be expand at run time. The panel paint method I have used is as below.When I run the program it draws lines, but when I scroll down the panel the lines get crashes.How can I avoid that? private void panel1_Paint(object sender, PaintEventArgs e) { this.DoubleBuffered = true; Pen P = new Pen(Color.Red); for (int i = 0; i < 10; i++) { e.Graphics.DrawLine(P, (new Point(i * 40, 0)), (new Point(i * 40, 60 * 40))); } for (int i = 0; i < 60; i++) { e.Graphics.DrawLine(P, (new Point

I would like to create a panel from a dataset that has one observation for every given time period such that every unit has a new observation for every time period. Using the following example: id <- seq(1:4) year <- c(2005, 2008, 2008, 2007) y <- c(1,0,0,1) frame <- data.frame(id, year, y) frame id year y 1 1 2005 1 2 2 2008 0 3 3 2008 0 4 4 2007 1 For each unique ID, I would like there to be a unique observation for the year 2005, 2006, 2007, and 2008 (the lower and upper time periods on this frame), and set the outcome y to 0 for all the times in which there isn't an existing observation,
