    I want to plot some data. The first column contains the x-data. But matplotlib doesnt plot this.

  • JLabel which hides text after reaching certain length or number of values

    - by Patrick Kiernan
    The purpose of the JLabel is to show who a message is to, like in a mail client e.g. To: John, Mary, Peter, Frank, Tom, Harry I will have the names in a vector so can build up a string from that and then set the label's text to this string. However it has the potential to get quite long. I was think it might be nice to have something like this: To: John, Mary, Peter, Frank, Tom, Harry, ... Then when you click on the '...', it will expand more or just show a tool tip if you mouse over the ... Yes this idea is stolen from Thunderbird! I am open to other ideas, don't have to use a JLabel. Thanks.

  • CSS Margin/Padding Issue on Browser Zoom

    - by korymath
    I am having difficulty getting my page to show up correctly at various browser zoom settings. http://andstones.ca/newsite The content is aligned if the user is zoomed out on the page, but once they zoom too far out and refresh the page, or if they are too zoomed in and the page loads, then the content pane is shifted. This does not seem to be an issue in firefox, but it is a very serious issue in chrome/safari/iexplore and on the iPad. What can I do to ensure that the main content loads in the correct position regardless of user browser settings? Thanks , Kory

  • Implementation of any Hamiltonian Path Problem algorithm

    - by Julien
    Hi all ! Here is my problem : I have an array of points, the points have three properties : the "x" and "y" coordinates, and a sequence number "n". The "x" and "y" are defined for all the points, the "n" are not. You can access and write them calling points[i]-x, points[i]-y, points[i]-n. i.e. : points[i]->n = var var = points[i]->n So the title maybe ruined the surprise, but I'm looking for a possible implementation of a solution to the Hamiltonian path problem : I need to set the "n" number of each point, so that the sequence is the shortest path (not cycle, the edges have to be disjoint) that goes exactly once through each point. I looked for a solution and I found The Bellman Ford Algorithm but I think it doesn't work since the problem doesn't specify that it has to go through all of the points is it correct ? If it is, does somebody has another algorithm and the implementation ? If the Bellman Ford Algorithm works, how would I implement it ? Thanks a lot, Julien

  • NSString sizeWithFont: returning inconsistent results? known bug?

    - by Olof Hedman
    I'm trying to create a simple custom UIView wich contain a string drawn with a single font, but where the first character is slightly larger. I thought this would be easily implemented with two UILabel:s placed next to eachother. I use NSString sizeWithFont to measure my string to be able to lay it out correctly. But I noticed that the font baseline in the returned rectangle varies with +/- 1 pixel depending on the font size I set. Here is my code: NSString* ctxt = [text substringToIndex:1]; NSString* ttxt = [text substringFromIndex:1]; CGSize sz = [ctxt sizeWithFont: cfont ]; clbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, sz.width, sz.height)]; clbl.text = ctxt; clbl.font = cfont; clbl.backgroundColor = [UIColor clearColor]; [contentView addSubview:clbl]; CGSize sz2 = [ttxt sizeWithFont: tfont]; tlbl = [[UILabel alloc] initWithFrame:CGRectMake(sz.width, (sz.height - sz2.height), sz2.width, sz2.height)]; tlbl.text = ttxt; tlbl.font = tfont; tlbl.backgroundColor = [UIColor clearColor]; [contentView addSubview:tlbl]; If I use 12.0 and 14.0 as sizes, it works fine. But if I instead use 13.0 and 15.0, then the first character is 1 pixel too high. Is this a known problem? Any suggestions how to work around it? Creating a UIWebView with a CSS and HTML page seems way overkill for this. and more work to handle dynamic strings. Is that what I'm expected to do?

  • Div overflow not hidden properly

    - by bbeckford
    Hi guys, I'm working on this site - http://dev.chriscurddesign.co.uk/mayday It works in everything other than IE7 and IE8 in compatibility mode (don't care about IE6), where the vacancies lists on the right aren't hidden correctly by their parent overflow property. I have been pulling my hair out trying to get to the bottom of this, its driving me up the wall, anyone got any ideas whatsoever? Below is an image of the issue, chrome on the left, IE8 compat mode on the right. Cheers, -Ben

  • Right to Left UI in iPhone (Hebrew)

    - by Reflog
    Hello, I'm struggling in creating a RTL UI in iPhone application. The framework doesn't seem to have any support for RTL languages. The only thing is the alignment inside labels, which is nice, but it conflicts with other controls behaviour. The question is: Is there a working code for a RTL TableView? Something that would handle the disclosure buttons to be on the left, section titles to be right aligned, index view to be left aligned? As far as I understand I cannot move the index view of the tableview, i have to overlay some custom control... Any suggestions/pointers/examples? p.s. this is not a duplication of this question: http://stackoverflow.com/questions/1677988/right-to-left-alignment-for-uitableview since what I am looking for is a deeper customization, not just a new type of CellView. (Update: Mar 10) For now - I've removed support for indexView from the tableView at all, implemented the cells as custom views by myself (with disclosure buttons on the left), and customized the header/footer of the table as well. the only thing that is left is the Index View. Thanks in advance!

  • 100% width bg images not extending on horizontal scroll

    - by Fuego DeBassi
    I'm noticing this issue. I made a quick screen capture to demonstrate: http://dl.dropbox.com/u/904456/2010-06-14_2323.swf Basically when you have a min-width set and the viewport goes under that constraint, a horizontal scroll bar appears. Pretty much what you would expect, but when you scroll over horizontally all elements that are suppose to extend across the entire width of the page and have background images/colors different from the body do not extend. If you resize the viewport it seems to catch up. Is this a known issue? You can see it on a lot of sites, http://gowalla.com for example. Any ideas?

  • Dojo: Programatically setting checkbox label for adding on TableContainer

    - by Det
    Hi there, after some hours of checking out documentation, I am somewhat desperate: Basically I need to populate a TabContainer with some TextBoxes, and some Checkboxes. All theses neatly arranged: Labels to the left, fields to the right. To have this done I use a TableContainer that I add to the TabContainer, create the TextFields and add them to the TableContainer. All is rendered ok. But when it comes to a checkbox, I can't find the trick to have a label displayed at all. If I: - add a label-attribute to creation statement say: var text8 = new dijit.form.CheckBox({ id:"zuschauer_" + i, value: "zuschauer", label:"fritt"}); Firefox comes up with a "containerNode is null" - Error try to add a tag: Nothing is shown (no error, but alas: no label): var text9 = dojo.create('<label>'); dojo.attr(text9,"for","zuschauer_" + i); dojo.attr(text9,"content","fritt"); try to add a div or somewhat else on the tablecontainer (disabled Labels): Firefox comes up whith: Error: uncaught exception: [Exception... "Component returned failure code: 0x80004003 (NS_ERROR_INVALID_POINTER) [nsIDOMHTMLDivElement.appendChild]" nsresult: "0x80004003 (NS_ERROR_INVALID_POINTER)" location: "JS frame :: ... same is for created TextNodes... So how the hack: - Would I generate a label to a checkbox programatically (no html template possible, I've seen the code around, creating a checkbox but having a 'label for' on the html before. This would not be helpful, as I don't know how many checkboxes I need at designtime. These are to be genereated completly at runtime. - Would I have this very simple design done programatically, Must be easy, this is not rocket sience. Do I really need the TableContainer to have this done? - Can I create static text in a TableContainer? Any hint would be helpful Desperate Det

  • WPF: Aligning the base line of a Label and its TextBox

    - by Heinzi
    Let's say I have a simple TextBox next to a Label: <StackPanel> <StackPanel Orientation="Horizontal"> <Label Margin="3">MyLabel</Label> <TextBox Margin="3" Width="100">MyText</TextBox> </StackPanel> ... </StackPanel> This yields the following result: As you can see, the base lines of MyLabel and MyText are not aligned, which looks ugly. Of course, I could start playing around with the margins until they match up, but since this is such a common requirement I'm sure that WPF provides a much easier and more elegant solution, which I just haven't found yet...

  • Piano Keys using GridLayout (or Something Else)

    - by yar
    I am creating a container of JComponents which will look like a piano keyboard. The black keys look like this (Groovy) def setBlackNotes(buttons) { def octaves = (int)(buttons.size() / 5) def gridLayout = new GridLayout(1, octaves*7); def blackNotePanel = new JPanel(gridLayout) this.add blackNotePanel def i = 0 octaves.times { 2.times { blackNotePanel.add buttons[i++] } blackNotePanel.add Box.createHorizontalBox() 3.times { blackNotePanel.add buttons[i++] } blackNotePanel.add Box.createHorizontalBox() } } Which is just what I need, and looks like this: but then I'd like to move this over to the right by half-a-key width. All of my attempts to move the blackNotePanel over by an arbitrary width -- wrapping it a BorderLayout, a MigLayout, etc. -- have failed or changed the spacing of the GridLayout radically. Any suggestions on how to move this over to the right by an arbitrary amount in pixels?

  • How to ellipsize center-aligned textview beside a right-aligned button when screen width is small

    - by simplymoody
    ------------------------------------ | LONG_TITL... |button| | |------------------------------------| | | I have an app header which consists of the app title and a button. The button should be fixed on the right side but I want the title to be in the middle and ellipsize when the screen is too small. Problem is the title just won't ellipsize even though the button is nearly beside it. Here's what I have so far: <RelativeLayout android:id="@+id/headr" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center"> <ImageView android:id="@+id/bar_orange" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:minHeight="40dp" android:scaleType="centerCrop" android:src="@drawable/bar_orange"/> <TextView android:id="@+id/Title" android:layout_marginLeft="20dp" android:layout_marginRight="20dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:gravity="center" android:text="@string/bcd" android:textColor="#FFFFFF" android:ellipsize="marquee" android:singleLine="true" android:textSize="18sp" android:textStyle="bold"/> <Button android:padding="5dp" android:id="@+id/home" android:textColor="#ffffff" android:layout_marginRight="10dp" android:layout_marginLeft="10dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_centerVertical="true" android:singleLine="true" android:background="@drawable/button_home" android:text="@string/home"/> </RelativeLayout> Is there a way to do this with just RelativeLayout?

  • flow 2 columns of text automatically with CSS

    - by Joseph Mastey
    I have the code similar to the following: <p>This is paragraph 1. Lorem ipsum ... </p> <p>This is paragraph 2. Lorem ipsum ... </p> <p>This is paragraph 3. Lorem ipsum ... </p> <p>This is paragraph 4. Lorem ipsum ... </p> <p>This is paragraph 5. Lorem ipsum ... </p> <p>This is paragraph 6. Lorem ipsum ... </p> I'd like to, without markup if possible, cause this text to flow into two columns (1-3 on the left, 4-6 on the right). The reason for my hesitation to add a column using a <div> is that this text is entered by the client via a WYSIWYG editor, so any elements I inject are likely to be killed later on inexplicably. Thanks, Joe

  • Outer class jframe is not hiding when calling the inner class jframe

    - by user2909960
    When i am calling the inner jframe, it is called, but outer jframe is not hiding. instead it gets overlapped. so what will be the solution for this. Is there any way to get out of this. As i tried when i am calling the inner class frame, the outer class frame is also called, and it is not hidden. package com.exp.example; import java.awt.Color; import java.awt.Container; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JTextField; @SuppressWarnings("serial") public class A extends JFrame implements ActionListener { JFrame rframe = new JFrame(); JLabel CFirstName; JTextField Cfname; JButton jbsubmit; Container cp; public A() { rframe.setSize(500, 200); rframe.setLocationRelativeTo(null); cp = getContentPane(); cp.setLayout(null); setSize(550, 300); rframe.setTitle("Outer Frame"); cp.setBackground(new Color(140, 180, 180)); CFirstName = new JLabel("First Name"); Cfname = new JTextField(10); jbsubmit = new JButton("PREVIEW"); CFirstName.setBounds(10, 20, 100, 35); Cfname.setBounds(150, 20, 150, 25); jbsubmit.setBounds(190, 110, 92, 25); cp.add(CFirstName); cp.add(Cfname); cp.add(jbsubmit); jbsubmit.addActionListener(this); rframe.add(cp); rframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); rframe.setVisible(true); } public void actionPerformed(ActionEvent ae) { String action = ae.getActionCommand(); if (action == "PREVIEW") { /* Write the code here * When we click on preview button the frame of outer class(class A) gets * deactivated(closed) and inner frame, frame of inner class(class B) gets visible. * it should not be overlapped. */ /* My Code */ new B(); rframe.setVisible(false); } } public class B { JFrame frm = new JFrame(); Container cp; public B() { frm.setSize(500, 200); frm.setLocationRelativeTo(null); cp = getContentPane(); cp.setLayout(null); setSize(550, 300); frm.setTitle("Inner Frame"); cp.setBackground(new Color(140, 180, 180)); JLabel cpn = new JLabel("hello"); cpn.setBounds(10, 20, 100, 35); cp.add(cpn); frm.add(cp); frm.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frm.setVisible(true); } } public static void main(String[] args) { new A(); } }
