panel

I try to give the user a 'clean and simple' interface by hiding some elements. Only a small arrow denotes that he can expand some part of the main menu bar. When all is closed it looks like this: When you open all it looks like this: Each arrow is a SpeedButton thats sits on the left side of a panel. By clicking on the button the Width is toggled between the width of the Speedbutton (closed) and the width of the panel at design time (open). The width of the panel at designtime is stored as a constant. The procedure show_hide_controls handles this: procedure TCompose_Main.show_hide_controls

I'm working on an app where having a "drawer" on the left-hand side would be very beneficial. I'm doing some initial testing to see how I would best accomplish this, and I'm having some very basic trouble. My Setup 1. I am using a single-view application template in Xcode 4. 2. To the xib's "main/border" view, I've added 2 UIViews (LeftPanel and RightPanel) and a UIButton (ShowHideButton). 3. I've colored the LeftPanel green and the RightPanel blue for easier visibility. 4. When the view is loaded, both panels are visible and the UIButton has the text "Hide Panel". 5. Upon pressing the button,

I want to display data with level of detail, so i use a TreeView, but each detail is quite short, so i would like to use a WrapPanel (horizontal) to have many details per line. Something like : This is an unexpanded item This is The Header of an expanded item Info 1 Info 2 Info 3 Info 4 Info 5 Info 6 Info 7 So i tried defining TreeViewItem's Template but i could not get the wrappanel to wrap. I have only one info per line, when info's datatemplate width is 100 and TreeView is 500. i tried setting Width of WrapPanel, ItemsWidth, are other things with no success. Any idea ? EDIT : i finally got

I have a problem when trying to draw to a panel immediatly after calling a panel.Update(); Here's the code: public void AddAndDraw(double X, double Y){ AddPoint (X, Y); bool invalidated = false; if (X > _master.xMaxRange) { _master.Update (); invalidated = true; } if (Y > _master.yMaxRange) { _master.Update (); invalidated = true; } if (!invalidated) { _master.UpdateGraph (this); } else { _master.PaintContent (); } } When running this problem I only see the cleared panel and not he content I'm trying to paint in the .PaintContent()-method. I've already tried using .Invalidate() and .Refresh()

I am trying to use Flexboxes in order to strech a panel I created using Materialize. This is the html that creates my panels: <div class="row"> <div class="col s6"> <div class="card-panel"> panel1 </div> <div class="card-panel"> panel2 </div> <div class="card-panel"> panel3 </div> </div> <div class="col s6"> <div class="card-panel"> panel4 </div> </div> </div> And this is the result: Now I would like to strech panel4 in order to make it flush with the bottom of panel3 . Probably this is possible using Flexbox but I can't figure out how to get Materialize and Flexbox to work together Materilize

I'm drawing a panel on a bitmap in picturebox using C#. I used below code, which is fine when I don't minimize the Form. When I minimize the Form and again maximize it to the first size, all panels which were drawn by this class, show black background. I found that when I change ControlStyles.Opaque to something else such as "SupportsTransparentBackColor" the problem would be fixed but the panels would not be transparent anymore. public class ExtendedPanel : Panel { private const int WS_EX_TRANSPARENT = 0x00; public ExtendedPanel() { SetStyle(ControlStyles.Opaque, true); } private int opacity
