Add text dynamically to the SplashScreen...

Hello

I use the splash screen that opens during my xml application that loads all of the HTTP connection.

This start screen is controlled by a timer thread which, after some specific time, transfer to the landing screen.

I would like to add different text based on the time spent on the thread of Splash.

My current thread is 32 seconds. I want after 10 seconds, I'd write "Loading News... »
After 20 seconds, I should write "loading settings...". "after every 10 seconds etc. Then, total three changes will come during the time splashscreen transfers control to landingscreen.

How can I achieve this. Post my code, which will help you understand the requirment.

First file with UiApplication

public class NewsArena extends UiApplication
{
    public static void main(String[] args)
    {
        NewsArena hello = new NewsArena();
        hello.enterEventDispatcher();
    }
    public NewsArena()
    {
        pushScreen(new WelcomeScreen(this,new LandingScreen(Constants.NEWLYADDED)));
    }
}

Have the second class SplashScren

public class WelcomeScreen extends MainScreen
{
    private UiApplication application;
    private MainScreen next;
    private static final Bitmap _bitmap = Bitmap.getBitmapResource("wap_logo.gif");
    private Timer timer = new Timer();

    public WelcomeScreen(UiApplication application, MainScreen next)
    {
          this.application = application;
          this.next = next;
          this.add(new BitmapField(_bitmap,BitmapField.FIELD_HCENTER | BitmapField.FIELD_VCENTER));
          this.add(new LabelField("Loading application ....",LabelField.FIELD_HCENTER | LabelField.FIELD_VCENTER));
          timer.schedule(new CountDown(), 32000);
    }

    public void dismiss()
    {

        timer.cancel();
        application.popScreen(this);
        application.pushScreen(next);
    }
    private class CountDown extends TimerTask
    {
        public void run()
        {
            DismissThread dThread = new DismissThread();
            application.invokeLater(dThread);
        }
    }

    private class DismissThread implements Runnable
    {
        public void run()
        {
            dismiss();
        }
    }
}

Thus, instead of

"Loading application...". "I want to add other texts defined above, on the basis of time expired on SplashScreen.

Thank you

Kind regards

In your SplasScreen, use the following for Timer constructor:

hourly (task the TimerTask, delay, long)

Schedules the task specified for the repeated execution of fixed / period, starting after the specified delay.

Then task will be continuously called after the time (period) specified.

And in the TimerTask:

1. change the text of the label.

2. If the total time of the display is greater than your total time then make disappear the splash screen.

You can try with something like below:

public class WelcomeScreen extends MainScreen{    private UiApplication application;    private MainScreen next;    private static final Bitmap _bitmap = Bitmap.getBitmapResource                                           ("wap_logo.gif");    private Timer timer = new Timer();

    //display the messages in the following order (0,1,..., 4,0,..)    //toggle after 1 second    private String msg[] = {"Loading 1", "Loading 2","Loading                              3","Loading 4","Loading 5"};    int totalMessage = msg.length;    int currentMessageIndex = 0;    int timeBetweenToggleMessage = 1000;

    long startTime;    int totalTime = 32000;

    LabelField labelField = new LabelField(msg[0], DrawStyle.HCENTER |                                                           LabelField.USE_ALL_WIDTH );

    public WelcomeScreen(UiApplication application, MainScreen next)    {        startTime = System.currentTimeMillis();        this.application = application;        this.next = next;        this.add(new BitmapField(_bitmap,BitmapField.FIELD_HCENTER |                                          BitmapField.FIELD_VCENTER));        this.add(labelField);        timer.schedule(new CountDown(), 0, timeBetweenToggleMessage);    }

    public void dismiss()     {

        timer.cancel();        application.popScreen(this);        application.pushScreen(next);    }    private class CountDown extends TimerTask     {        public void run()         {            synchronized(Application.getEventLock())            {                if(currentMessageIndex >= totalMessage )                      currentMessageIndex = 0;                labelField.setText(msg[currentMessageIndex]);                currentMessageIndex++;                long currentTime = System.currentTimeMillis();                if ( currentTime - startTime >= totalTime)                {                    DismissThread dThread = new DismissThread();                    application.invokeLater(dThread);                }            }        }    }

    private class DismissThread implements Runnable     {        public void run()         {                        dismiss();        }    }}

Add text to change the field

Hello

I display a text field on a screen. Is it possible to add the user to add text to the editfield, even if the focus is on a button. So, no matter where the cursor is on the screen if the user types the text it is automatically sent to the editfield. Is this possible?

Thank you

I think it's possible. You can issue a setText at any time update the field. The trick is to get and then the interpretation of characters.

To give you an easy solution. say that you override keyChar to your screen. This will get the control regardless of the field is in fact in short. So, you could do something like this (untested, no compiled code, as only learning tool):

{} protected Boolean keyChar (char c, int status, int time)
String current = myEditField.getText ();

String = new current + c;

myEditField.setText (new);

Returns true;

}

There are problems with this, for example, how do you get back?

Another option is to replace keyDown and if the focus is not on the EditField, set it to the EditField. Then the EditField will receive all methods keyChar itself and treat them properly.

See Doc.addField. If there is a model for the positions lines on each page, then you can generate the positions in JavaScript and use Doc.addField to set the text fields.

PDF fillable where the customer can add text AND change the fonts?

Hello
I would like to be able to provide my clients with editable poster templates. I created in InDesign posters, with a large white space in the middle where they can add their own texts, and when they're done, they can send them to the printer. The problem is, I just want to give them - in PDF print quality, so they don't mess up my share of the design (in addition, they are not sufficiently advanced to use indesign or illustrator or something like that).
I tried implementing a PDF file using a text field, but it won't work. When the customer type in the text field, they will not be able to change the size of font, color, weight, etc.
Is there some sort of 3rd party plugin that will allow me to create PDF files to fill live where the customer can indeed choose their fonts & things when they fill in their info?
Thank you!

Bernd: rich text only allows to apply bold, italic, exposing. It does not allow the user to make the text larger or to change the font.

Cannot add text to all the

Hello... I use Photoshop Elements 8 and use items from version 2. For about the last 6 months, I couldn't type any text at all. When I try to type any text, images, newly created, scanned in or otherwise - no text appears. When I click on the image to start typing, I get the little box that always pointed, but no text appears when I type. I am quite familiar with the elements and have no idea of what brought this. I don't remember all the settings changes and I checked all the settings I can think. All other functions seem to work.
No matter what the police, or the font size is selected, the color of the text changes make no difference, I checked the horizontal, vertical and hide the text settings, opacity has been verified... I'm fresh out of ideas. I even uninstalled and reinstalled the software - nothing - no text at all.
I use Windows 7. I would like suggestions.

Dynamic text: gradually change the size of font that you type

Always present in my project. I need help with that.
I have a dynamic txt connected to a keyboard on the screen, and I need the police to shrink in size according to the number of characters that you enter.
Looks like it could be a simple algorithm, but I have no idea where to start.
any help?

If you use a keyboard on the screen, I'm not sure that a listener CHANGES will work if it involves adding text to the textfield with code... but kGlad know better on this subject. If she does not have a code, code adds text can have the task of checking the length right after each character is added.

To check the number of characters in the textfield by its length property, essentially use something similar...

numCharacters = yourTextfield.length;

Add link to URL in the text added to the catalyst

Hello
My question is, is it possible to be part of a text added in flash catalyst a link to the URL, as in normal site?
Thanks in advance!

Hello

I'm sorry, I'm not very clear about your question. So, I'll give you two solutions. Please use that is appropriate for you

Solution 1: This is to convert any instance of text unique all in Flash Catalyst to a clickable link

You can convert any occurrence of text in a button & then add a "Go To URL" interaction to achieve this.

Step 1. Add text by using the text command.

Step 2. Select the text and convert it into a "button" with Heads Up Display.

Step 3. Click on the button 'Add the Interaction' in the Panel "Interactions".

Step 4. Select "Go To URL" from the second drop-down list and enter the URL in the text box below the

Solution 2: This is to convert part of the occurrence of text to a clickable link.

This feature is available only by the "RichEditableText" component that is not supported by Flash Catalyst.

Once you have the text placed inside your application using catalyst, you must edit in Flash Builder.

Step 1. Save the project in Flash Catalyst under FXP

Step 2. Import the FXP in Flash Builder file, by using the menu "File-> Import Flash Builder Project"

Step 3. Open the file "Main.mxml" & look for the component "RichText".

Step 4. Replace "RichText" with "RichEditableText.

Step 5. Set the 'editable' component "RichEditableText" property to "false".

Step 6. Add the tag "" around the part of the text you want to be clickable. See example below

Step 7. Save & publish the project using the menu "project-> Export Release version.

You cannot change the properties of TEXT elements. Instead, you can use the TEXT_ITEM guests to display the legend.

Add text in Photoshop Elements 14

I add a text layer and can not add text to an image. The file may be a photoshop, JPEG or PNG file? When I try to add text, I see the point in the cursor and there is no text if displayed, after that I typed in.

Pt font size may be too small for the resolution of the image file.

You are not limited to the default size in the drop-down list in the text tool options bar.

Highlight the value on the display and then type in a lot - try 110 or 140 - and see if it shows up. The text should be on a separate layer.

Is there an easy way to add text to a chain control / indicator and keep the colors

Hello

Bassically I want to add text to a chain control / indicator without losing the formatting of the previous text.

For a part of a program that I create, data will be transmitted to and from a serial device. I want to display this data in a chain control / indicator and change the color of the text of certain strings depending on data type (sent, received). Basically as a nice log window.

At the moment, I update the chain control / indicator by reading the text and concatenated with the new string. However, this method removes the colors of previous text :-(

Is it possible to add data to the control of the chain / indicator without losing the text previous formatting?

I started to create a sub vi who reads a text both character and adds a new element in an array (offset color and text), if the color is distinguished by the previous character. Only problem is it seems to be quite time CPU.

Thanks in advance,

Matt

Actually, no. This means that you will have to use workarounds. Your workaround solution seems a bit involved. Basically, all you need to do is just to keep track of the pairs of end start/selection selection that must be colored in a table. Then just you loop in this table to color the text marked by the power positions.

An alternative is to use a different indicator. Rather than an indicator of the string, you can use a table with a column. You can then set the foreground color on a cell by cell basis, and add a new line (row) will not affect the coloration of the previous lines.
