EditField when it is full the text does not scroll
Hello
Below custom editfield extends EditField. My problem is that the user Pat and field gets complete with text, when the user reaches the end of visible display of the field the text scrolls does'nt user types continuously.
Should I use a different type of field?
Any help much appreciated.
SerializableAttribute public class CustomEditField extends EditField {}
private members of the class CustomEditField
defaultFont fonts private;
used to get the default font
private string text;
private int width;
used to specify the default width of the table cells
constructor calls the constructor of the superclass
public CustomEditField (label As String, String initialValue, int maxNumChars,
long style, int width) {}
Super (label, initialValue, maxNumChars, style);
This.Width = width;
}
replaces the functionality of getPreferredWidth default to return to a fixed rate
Width
public int getPreferredWidth() {}
/ * defaultFont = Font.getDefault ();
Text = "0000000000";
Return defaultFont.getAdvance (text); * /
return this.width;
}
replaces the default layout features to set the width of the table
cell
Protected Sub layout (int width, int height) {}
width = getPreferredWidth();
height = super.getPreferredHeight ();
Super.Layout (width, height);
uses the features available to the superclass
Once the width and height defined
super.setExtent (width, height);
use the functionality of the super class setExtent
Once the width and height defined
}
{} public void paint (Graphics graphics)
graphics.setBackgroundColor (Color.LIGHTBLUE);
Super.Paint (Graphics);
}
}
width = getPreferredWidth() inside the layout is the main problem. With this line you ignore Manager parent giving your text box the width of your choice (Integer.MAX_VALUE > 1) and tell him «no, I'll work in this width largely only» If you want to limit the width of the gadget, limit the width of the OneLineTextField with
protected void sublayout(int width, int height) { super.sublayout(Math.min(width, this.width), height); }
Of course, private int width should be in OneLineTextField, not CustomEditField. This will allow you to deposit your CustomEditField either. If you want your LIGHT blue background, create the OneLineTextField like this:
OneLineTextField tweetTextField = new OneLineTextField("", 140, width) { protected void paintBackground(Graphics g) { int prevBgColor = g.getBackgroundColor(); g.setBackgroundColor(Color.LIGHTBLUE); g.clear(); g.setBackgroundColor(prevBgColor); } };

Hi, I have a problem with this page. http://reystyler.com/kwekjong/citrus-calamondin.html
I pin the text because I want to keep it in the right place. But now the text does not scroll, and the page is changing.
Can you help me?
best regards Jan
It looks like you want a page aligned left, rather than the default behavior, which is centered.
Disable the PIN on all points. SIte properties (or Page for a specific page properties) uncheck the option "Center horizontally.
Now, your content will be left-aligned in the browser and scroll normally.

IPhone 6 IOS 9.3.1 does not ring when a call comes, neither text does not sound a notification.
Have you checked the obvious things? E.g.Ring/Silent switch on the left side is not on? Control the volume of ringtone under settings/sounds?
If they are not serious then have you tried power the phone off and on again? Other sounds work fine, or if all sounds are dumb? for example can play you music through the speaker?

Touchpad on the laptop does not scroll upwards or downwards
The touchpad on the laptop does not scroll upwards or downwards, I was offline for 5 weeks that my router broke out between the change of operator, so I had to wait for another.
When I was on the touch pad was'nt working properly. I can't do a system restore, because that would be the former provider. Ideas anyone please?First, check the scrolling settings in the advanced settings of Touchpad.
If they are enabled, uninstall the mouse/keyboard 3rdparty as Logitech or Microsoft and Watcom drivers that may have installed you.
If it's no good, uninstall the Toshiba touchpad driver, then download and install the latest version.

event when the text does not fit in the field
Hello
When there is not enough room for the text in a field. Player will show a little "+". Is it possible to listen to this as an og event something similar?
I have a field with room for 3 lines. If the user enters several. I need to supplement in anoter field.
I sense that looking for the number of lines - I do a split for '\r' and get each row in a table. BUT the lines can be long, so just som enter 1 long line, my logic does not work. My policy is NOT monospaced, so I know how long a line!
Let me hear if someone solved a case like this
Thank you
Thomas Groenbaek, Jyske Bank, Denmark
If you check the box 'Time limit to the Visible area' on the ground, the complete event fires once the user fills out the field. You can put in a script like:
xfa.host.setFocus (form1.subform1.overFlowTextField);
in the complete event of the field with room for only 3 lines. Be aware though, that the focus change is not instantaneous and that a character or two could get lost, especially if the user is a fast typist. To make this work, you need to be "Limit length for area Visible" checked.

When I hover over a reminder, the text does not appear as before.
I'm used to be able to hover on a sticky note and the arisen text box. Now all I get is a black slider. I have to actually click on the note to get the text.
Go to Edit - Preferences - commenting on and check the box that says automatically "open menus inlaid on the mouseover.

Header running including the text does not appear
I have a table with a number of lines, each one for a different product. Each product has a type of product. The type of product does not anywhere in the line. But I want to use the product type in a header running on the master page. Is there a way to make the hidden text, it can be picked up by the variable header running but not displayed in the cell where it is defined? Or y at - it another way to accomplish what I'm doing?
I'm generating the table programmatically, so it is easy to add type of product with a character style for the text of the first cell in each row. I don't want just the product of the first cell to display type part.
Thank you!
Unlike a table of contents that can be non-printable text, I don't think that a variable will do that, using the method of Willi to make it invisible is so logical. I would go a little further, however, I think and place this information into something anchored in one of the cells. Set the positioning custom, so it has no effect on the flow of text.
I would define also an object for these anchored frames style that has both a definition of position to the anchored object, so you don't need to do all the time, and the good assigned paragraph or character style to be picked up by the variable. During the editing phase, I would define it as red or another contrasting color so that you know that you will see if it is present and will be able to spot when he is away and then change the style definition to give the text a fill [None] just before the release.
