The multi display a line of text in the list or the selector?

Hi guys,.

Is it possible to display several lines in lists of QNX?

When I try to add a newline '\n' in the string, it gets shows ever, even when I try to increase rowHeight.

Any help would be appreciated.

Thank you.

Oddly enough, I was able to do this... but not in front of my computer to dev

Thanks dropbox!

Try the following for your cellRenderer class

package
{
    import flash.text.TextFieldAutoSize;

    import qnx.ui.listClasses.AlternatingCellRenderer;

    public class rssCellRenderer extends AlternatingCellRenderer
    {
        public function rssCellRenderer()
        {
            super();
        }
        override protected function onAdded():void
        {
            super.onAdded();
            this.label.autoSize = TextFieldAutoSize.LEFT;
            this.label.wordWrap = true;
            if (this.label.textWidth > this.width)
            {
                var charPerPixel:Number = this.label.text.length / this.label.textWidth;

                var charMax:int = Math.floor(charPerPixel * this.width) - 3;

                this.label.text = this.label.text.substr(0,charMax) + "...";
            }

        }
    }
}

It is not perfect, but I use it when grabbing RSS feeds (because they tend to be multliline). This helps to keep the titles within the area (the best he can, it always tends to overflow if there is a lot of text). If all goes well it gives you a starting point well!

  • How to add lines of text information in the settings?

    Guys,

    I'm trying to customize a few things about Motion 5 and really I was wondering how to add these lines of text in the settings?

    Tried to google it, but without success.

    I think you need to learn how * write * FxPlug effects plugins. You cannot add these labels/buttons on the move as it is. What I usually do, is create a platform > pop up widget and use remove the "Snapshot" texts... "(and usually replace it with a series of quadratins (---) to create a line of separation.) To help you, you must have a 'sex' you can show/hide with opacity (and a rig box) which displays the help text.

    Hi all

  • How to position programmatically multi line of text in a string indicator

    Hi all

    I have problems of command positions of multiline text programmatically in an indicator of the chain. The goal is to have X and coordinated is who will control the multiline text programmatically positioned in an indicator of the chain. So, for example if I have a line of text multi as shown below in the first box, I'd like to be able to control programmatically if I can get a comparable result shown in the second box below. Sorry that I used a simple rectangle box representative indicator of string, but I am currently not to work if I was unable to copy the actual string indicator, however I think you guys got the idea.

    Thanks a lot for helping me.

    All you need to do is insert (or remove) the spaces at the beginning of the lines.

  • How can I display the printable two than non-printable ascii characters from a device and display it in a text box?

    Hello

    My send UUT to my computer via serial port of printable and non-printable ascii characters. The question is:

    (1) how to display all characters in a text box.

    (2) how can I display all these characters in hexadecimal format and display it in a text box?

    Thank you.

    Robert

    Text boxes can actually receive channels with printable and non-printable characters: nonprinting characters will be represented with a small square. For example, consider this code:

    tank has [512], msg [512];

    Create a string with embedded unprintable characters

    sprintf (one, "Hello: %c %c %c %c % c: World!", 1, 2, 3, 4, 5);

    Pass the string to the text box "such what."

    ResetTextBox (bH [1], b1_n, a);

    Format a hexadecimal representation of the string and add it to the text box

    FMT (msg, '\n%*d[zb1r16w2p0j1]', strlen (a), a);
    SetCtrlVal (Bosnia and Herzegovina [1], b1_n, msg);

    The result is as follows: the first line is the string passed "such what", what follows is the hexadecimal representation.

  • Wrap a line of text around the 3 sides of a "box" in 3D?

    AI CS6.

    If I draw a rectangle and you use extrude and bevel to create a 3D "box" shape, how to wrap a single line of text around three of the sides?  I created a symbol in the text and it shows in the selection of the "symbols" of the window of the dialog box "Veneer", but that one side of the 3D box is displayed at a time.  I expected to see a flattened shape box showing all six faces, so I could place accurately the line of text.  Similar to what you see when you look one way for a 3D object.

    It's even worse if I ask one edge beveled extrusion - there are 40 separate 'faces' to deal with.

    Ken

    It won't work the way you want.

    You can only map to a surface at a time so you'll match thre occurrences of the symbol manually.

  • Just updated to Sierra and updated Pages at the same time. Now when I try to select a line of text I find myself with an insertion point where I stopped by selecting

    Today, I updated for Sierra and updated to the latest version of the Pages. Now I find that I am more able to select a line of text. When I try to do, I find myself with an insertion point where I stopped by selecting, but nothing is selected. This is a bug in the new version of pages or get my wrong settings?

    You use a Wacom tablet by chance?

    Solution: Press the shift key, just before stop selection. And Yes, that sounds like trouble in the Sierra.

  • Why print preview and print lose lines of text from the image to the screen in the browser

    When I bring up (for example) a magazine article in my browser and you want to print it for future reference, print preview and printed image 'lost' lines of text between pages compared to the original image in the browser. For example: visit this link: http://www.pcauthority.com.au/Feature/408318, how-to-make-windows-admin-easy-with-powershell.aspx?eid=2 & edate = 20150828 & utm_source = 20150828 & utm_medium = newsletter & utm_campaign = weekly_newsletter & nl = weekly and select 'Print' from the menu. Print preview that appears - poster in portrait mode or landscape - loses one or two lines of text for the print version wraps useless. Where the missing text? pagination is not identical, and Firefox seems unable to handle it.

    I use a HP desktop with Intel i7 CPU 8 GB of RAM and Win 7 Pro SP1. Firefox is V40.0.3

    I do not see "imposed by the system of page breaks" encoded in this Web page. It would be difficult for an author of a Web page with an international audience.

    You use A4 paper, but what about those of us using letter-size paper? Page breaks may screw up page print to LETTER, from a Web site to THE like this.
    And what about the 'zoom' different levels? For printing which is called scale preview of Firefox and Page Setup print.
    I put systematically "modest" when printing to save paper, to keep the last page to only a few lines, or when the font size in print preview is too great (IMO) for printing on paper. And the size of police appeared to have worsened as monitor resolutions have gotten larger over the years.

    The only time wherever I lost lines of text between printed pages was when I was "pushing the limits" with the paper up and down / page margins. IOW, too small header / footer trying to get on each page as possible. By default, Firefox a. 5 "margins (left and right) with. 5 "header / footer (top and bottom margins) = letter-size paper. With 'A' type of paper using metric would be tantamount to the margins of 12.7 mm on all four sides. The /metric of inches "toggle" is with the size of the paper, the user has selected.

    Check the Page > margins & header / footer to see if you have the parameters of ~ 12mm or it they are smaller.

  • Trouble from the view of lines of text in Firefox, especially if you use AOL mail

    When you move the cursor around the email AOL email list, or around the text in a message, a few lines of text appear blurred: some letters are emboldened and other weakening. When you click on the affected area, he disappears to normal, but can return to blurred when the cursor is moved again. This sometimes happens on web pages too. It does not occur in Internet Explorer, however, so I don't think there is a problem with Firefox.

  • When I try to add text to a title block prior to a photo, it limits the amount of text that I can enter a line of text. How can I get to add more text?

    I'm doing a video for confirmation that has pictures on a soundtrack. I would add the persons name and bible passage before each group of students of photo. I am using the two lines of text slides so that their names are larger on top and their passages are smaller underneath. When I cut and paste in a try to type them in directly, it limited to about one line of text, even if there is plenty of room on the text box. Is how I can get to allow me to add more text?

    Try using the "scroll"Perspective it is a Star Wars style analysis and will be more text.

  • 114 the desire doesn't print all lines of text

    When you print an email (TEXT), my desire 114 printer prints all lines of text with the same quality.  Some of the lines are darker than others, some lines are barely readable or white, while some lines print only half the size of the font.  When I print a report of State printer, a few lines (like the lines 3, 6, 9 for example) do not print.

    I cleaned up, second level cleaned and aligned the printer several times without success.  Because it's consistent printing for printing when PRINTING TEXT, it almost seems like the printer receives no signal for some lines or print on paper areas.  If a JPG or image is printed, it prints in full.

    Any ideas?

    Thanks for your answer, but after all my attempts to clean the printer heads and firmly reinstall the black cartridge has solved my problem.  I think that the resettlement is actually what solved my problem because like I said in my previous post, it appeared that the printer would not print a few lines compared to others.

    Thanks again for your response.
