panel

I'm trying to write a custom Panel class for WPF, by overriding MeasureOverride and ArrangeOverride but, while it's mostly working I'm experiencing one strange problem I can't explain. In particular, after I call Arrange on my child items in ArrangeOverride after figuring out what their sizes should be, they aren't sizing to the size I give to them, and appear to be sizing to the size passed to their Measure method inside MeasureOverride . Am I missing something in how this system is supposed to work? My understanding is that calling Measure simply causes the child to evaluate its DesiredSize

I have a Panel in which some 2D objects are moving about. I have overridden paintComponent() as necessary. Now I want to be able to zoom in and zoom out that area. When zooming in, scrollbars will appear by which one can view the entire field by scrolling. While zooming in and out, the 2D objects should increase or decrease in size accordingly. Which Swing component or rather combination of components will help to achieve this? Easiest way is to modify your panel and introduce a double indicating your zoom level. This double would indicate your scale, where 1 is normal and higher is zoomed in.

I would like to extend a Panel frame of data along a minor axis in pandas. I start off creating a dic of DataFrame s to generate a Panel. import pandas as pd import numpy as np rng = pd.date_range('1/1/2013',periods=100,freq='D') df1 = pd.DataFrame(np.random.randn(100, 4), index = rng, columns = ['A','B','C','D']) df2 = pd.DataFrame(np.random.randn(100, 4), index = rng, columns = ['A','B','C','D']) df3 = pd.DataFrame(np.random.randn(100, 4), index = rng, columns = ['A','B','C','D']) pf = pd.Panel({'df1':df1,'df2':df2,'df3':df3}) As expected I, find I have a panel with the following dimensions:

I need to have panel behavior in chrome: something always on top but that does not impair the navigation (in any other way than masking a few pixels). We have two options at the moment: window in panel mode: not available yet (although it is available now to the GTalk extension ). window in popup mode: I can make it be always on top by refocusing at every event, however the focus will get targeted at my window (and impair the navigation) I'm looking for either: GTalk's dark magic A way to make a popup window stay on top (or come on top and relinquish the focus to the second topmost window) I

When I'm on the train to work I connect my netbook to my Nexus One's wifi hotspot. As I go through a tunnel my phone obviously loses it's 3G connection and takes a while to re-establish once the train emerges. But the netbook wifi logo stays constant as it's still connected to the phone itself. I've written a little python program that attempts to ping a server and thus decides if internet is available (feel free to suggest a method of detecting internet connection that would be either quicker or use less bandwidth as I am capped per month). My question is: how can I create an applet for GNOME

I have a panel on my frame .and by clicking on a button I want to delete the old panel and make the other panel and add that panel to my frame.(also I use netbeans) would you please help me that how can i do that?thanks JFrame frame = new JFrame(); final JPanel origPanel = new JPanel(); frame.add(origPanel, BorderLayout.CENTER); MouseListener ml = new MouseAdapter() { public void mouseClicked(MouseEvent evt) { // Mouse clicked on panel so remove existing panel and add a new one. frame.remove(origPanel); frame.add(createNewPanel(), BorderLayout.CENTER); // Revalidate frame to cause it to layout

I try to change a layout of the panel, but there are problems, because when I change layout the components remain on the panel and there are many bags. import java.awt.LayoutManager; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JPanel; public class LayoutTest extends JFrame { public LayoutTest() { initComponents(); } private void initComponents() { jPanel1 = new javax.swing.JPanel(); jButton = new JButton(); jPanel1.setBackground(new java.awt.Color(204, 204, 255)); jPanel1.setBorder(javax

I have built a semi-transparent custom layout panel in WPF by setting the Opacity value of the panel to 0.5. Everything works as expected, except that the children of the panel are also semi-transparent ! What do I need to change to have the children of the panel rendered without transparency? Here's the relevant code: public class DialogLayoutPanelControl : Panel { public DialogLayoutPanelControl() : base() { Background = Brushes.LightGray; Opacity = 0.5; } } Solution (by Anvaka): Background = new SolidColorBrush(Colors.LightGray) { Opacity = 0.5 }; Change the opacity of the brush, rather
