I want to ask how to set CCTextField placeholder and color.
I know it is easy to create a text field on spritebuilder, but it cannot set the text color and placeholder like UITextField.
yourTextField.textField.attributedPlaceholder = [[NSAttributedString alloc] initWithString:#"Placeholder String" attributes:#{NSForegroundColorAttributeName: [UIColor grayColor]}];
Same thing if you have to use the text too. Use the property .attributedText
When I had this problem I had to change a Cocos2d file:
cocos2d-ui/Platform/iOS/CCPlatformTextFieldIOS.m
- (id)nativeTextField
{
return _textField;
}
I would recommend just trying to use attributed string before changing cocos2d files. I'm using cocos2d v3 and xcode 6.1.1

I've created a small text editor window that allows the user to change some basic properties of a text area included within the screen. Two of the options available to change the properties of the textArea are font color and font color fill, which are both handled by separate color pickers.
I ran into an issue when testing these buttons using the setStyle method that only one property could be saved at a time. Example, if text color was set to BLUE, and afterwards fill color was set to YELLOW, text color would not remain blue, but instead revert back to its default defined in the stylesheet (black).
To fix this problem, I have created the following method;
private void updateTheSyle()
{
this.textArea.setStyle("-fx-control-inner-background: " + toRgbString(this.colorPickerFill.getValue()) +
"; -fx-text-fill: " + toRgbString(this.colorPickerFont.getValue()) + ";");
}
The toRgbString() method is also called, this is simply passing the user input from the color picker into a string such that the setStyle method can pass the correct parameters to the stylesheet.
This solution does work, as it enables me to change both the fill and the font color without reverting back to default upon selection. However, my program includes more than just fill and font color, which will contribute to a far longer setStyle statement as these options are added.
TLDR: Is there a way to edit a single style included in a CSS stylesheet without affecting the other styles in a given class?
For your first question (longer setStyle statement), If we take into account that the style is defined by a String, and it takes a whole set of details to provide for a single Style, so why not use a List<String> :
List<String> example = new ArrayList<>();
String style = "";
//For example if you use 2 textField to get the (value) and (type):
example.add("-fx-"+textFieldType+":"+textFieldValue + "; ");
//To gather all the properties in a single string
for(String property: example){
style += example;
}
yourNode.setStyle(style);
I do not know if there is a better approach but it works, good luck !
Edit :
I think this tip answers your second question:
private void Update(String type,String newValue){
for(int i = 0; i < example.size(); i++){
if(example.get(i).contains(type)){
example.set(i, "-fx-"+type+":"+newValue + "; ");
//Here you add a (break;) to not alter the other similar styles !
}
}
//Here you use a loop to update the new elements changed
}
I hope this will help you solve your problem !
When the user marks a text, he can define a backgroundcolor with the colorpicker (textcolor.plugin).
Once saved he can change the background-color but not get rid of it.
background-color:white is no solution as the bodycolor can be RGB or even a picture.
How is the colorpicker to configure to remove the style-tag or at least insert a background-color:none?
Found a solution changing the plugin (textcolor). If there is a better way please be free to post it.
I added additional colors to the colorpicker. The Color #FFFFFe (near White) i marked as NO COLOR and changed the plugin as shown.
function onPanelClick(e) {
var buttonCtrl = this.parent(), value;
if ((value = e.target.getAttribute('data-mce-color'))) {
buttonCtrl.hidePanel();
value = '#' + value;
buttonCtrl.color(value);
if (value == '#FFFFFe') { //Changing the value to -1 causes deletion :-)
value = -1;
}
editor.execCommand(buttonCtrl.settings.selectcmd, false, value);
}
}
Researched a bit more since the given answer did not work in my version 4.5.0 of tinymce.
The textcolor plugin uses 'editor.formatter.remove(...)' to remove text color or background color upon selecting 'x' in the last option of the color palette for 'no color'.
While that function is used elsewhere successfully in tinymce (e.g. when removing italics from text), in the context of the textcolor plugin it does not remove color formatting.
Solution:
Replace the following in the textcolor's plugin.js:
editor.formatter.remove(format, {value: null}, null, true);
with:
editor.dom.removeAllAttribs(editor.selection.getNode());
...or in the minified version plugin.min.js:
a.formatter.remove(b,{value:null},null,!0),
with:
a.dom.removeAllAttribs(a.selection.getNode()),
...and things start working as intended.

on line 915 I am trying
this.div_.innerHTML = sums.text + "some additional info";
but it doesnt reflect the additional text?
I tried doing what you showed, changing the innerHTML, on version 2.0.9 of the clusterer. (line 244). It adds the static text to the cluster icon.

Can I set the font size for string? I want to do text formatting for string, Is it possible in flex?
You can use TextField/UITextField to display formatted text. In both classes you have two options:
You can use setTextFormat() method to format text
You can use htmlText property to display HTML text. These classes don't support all HTML tags. Supported HTML tags are listed here.
If all you need to do is change the font, you can use the StyleableTextField class or the Label and set the . She can set the fontSize style of either class to globally change the font size.
No,
you need to set the font size of label or any text other Text control that you use to show string value.
var str:String = 'This is sample text';
//set in any method
lbl.text = str;
lbl.setStyle('fontSize', 20);
enjoy.
I'm trying to calculate how WIDE to make my button, based on the text that it will contain, and when I try to google for how to calcuate something as simplistic as the WIDTH OF SOME TEXT, I go cross-eyed just trying to wade through apparently nonsensical esoteric counter-intuitive voodoo. Can anyone out there help simplify for me how I would write a function like this:
public function HowWideWouldThisTextBeIfItWereInThisButton(Text:String,Container:Button):int {
...
}
Thanks in advance.
So long as you're in a UIComponent, you can use the measureText function.
public function howWideWouldThisTextBeIfItWereInThisButton(text:String,container:Button):int {
var lineMetrics:TextLineMetrics = container.measureText(text);
return lineMetrics.width;
}
That being said, the flex button component should automatically size to the width of the text, if you don't set a width on it. That way if you need the text width, you can just call use the textWidth property.
This works any format, size, font type. Don't forget properties "autoSize" and "wordWrap"!
var tf:TextField = new TextField();
addChild(tf);
tf.autoSize = TextFieldAutoSize.LEFT;
tf.wordWrap = false;
tf.text = "Whatever here";
tf.width = tf.textWidth + 4; // add 2 pixels-gutters left & right
Your button will need to be "tf.width" wide...
Here's how you do it in Spark:
I've modified - simplified - his example a bit here:
var textMetrics:TextLineMetrics = label.measureText( label.text );
var textWidth:int = textMetrics.width;
Here's a way that works also:
var tempText:Text = new Text();
tempText.regenerateStyleCache(false);
var textWidth:int = tempText.measureText(*yourstring*).width;
as I think, textField.textWidth construction works fine... until you change the font size.
It seems it calculates width based on 12px font.
So, if you have embedded font and global styling you can try fast solution:
var realWidth = myLabel.textField.textWidth * (fontSize / 12);
I've tried this on long and short strings and the result is correct.
Joshua, it really helps to be clear. Are you talking TextField, MX Label, Spark Label, RichText, etc? Different text components use different text engines, such as FTE and TLF and may have different solutions. I certainly wish Adobe had a good set of utilities or sample code which could predict what the size of font rendered onto the controls would be, before you actually do it. But, the good news is that in certain cases - like, a good old fashioned TextField, you can predict this pretty well. You just make a TextField, set it's textFormat field, auto size method and the text. You should be able to get it's size before adding it anywhere. I don't remember what the order was, but, I remember the order you set those properties matters. If you can't figure out how to do it, I can provide a code example. Now, for the new, "improved", components such as Spark Labels - I'll be buggered if I can find a damn way... spent a number of hours on this and haven't found a way.. or someone who knows a way :P.
Following up my comment on quoo's answer, here's the code for same purpose, but just grabbing the width out of a TextField, using TextLineMetrics as well:
public function mtxtWidth(container:TextField):int {
var lineMetrics:TextLineMetrics = container.getLineMetrics(0);
return lineMetrics.width;
}
Sounds like you could use textWidth
