I am developing xmpp-client app. One of the features is sending smiles and user should have ability to edit its like usuall text. Emoticons editing in Viber App is best example of what i want to implement.
I already tried three ways to solve problem:
I create emoticon like usual UIImageView and place it as a subview on UITextView using current caret rect. I use 5 whitespaces as a text placeholder in text view. There are two problems: with placing emoticons on new line when inserting text in the middle(printing whitespace not make caret move to new line); when user placing caret using magnify glass, he can move caret through emoticon(through 5 whitespaces), as delegate method not called during this process.
I have tried EGOTextView. There are problems with caret position and resizing when new line should be added. And there are some rendering artifacts when using it one line size.
I also have tried using UIWebView. But there were great problems with resizing based on text size and other artifacts with speed of response when becoming first responder.
May be some one could give me advice of really working solution?
Any suggestion please?
Thanks!

I'm trying to use TUI Image Editor (https://github.com/nhn/tui.image-editor) in my Cordova app on Android.
It is based on Fabric.js and overall working reasonably, however I have major problems with the text annotation: If the edited text is in the lower part of the screen, the Android softkeyboard is covering the text input and doesn't scroll it into view. This also happens when I run the page in the normal Android Chrome browser.
Are there any recipes or examples how to get that working with Fabric.js?
I had the same problem, and I just avoided using the IText and Textbox objects. I just used the html input field and object with type Text in fabric.js without editing inside canvas, and editing inside input and changing text object to input value. Because if you will use the IText and Textbox objects, you will face problems with editing text on small texts, or text objects with a small scale, where editing inside canvas will be difficult and annoying.
If you still want to scroll to text object I can't give you a full solution. But I think you can use canvas events for text
canvas.on('text:editing:entered', (textObject) => {
// calculate canvas offset and textObject offset and scroll to this position
})
I have a CodenameOne application which has a TextArea that should display a multi-line text.
When I run the app in the simulator and click on the text-area, the spacing between the lines and possibly also between the characters change so that the area that the text occupies shrinks a bit.
Why is this?
What should I do to prevent it?
That is due to the switch from our drawing to the native editing which will always render things slightly differently. E.g. things like line spacing are really hard to get accurately for every native device.
TextArea has a setRowsGap method that allows you to specify the spacing between rows in pixels but since this differs between OS's its probably not ideal.
Unlike most rich text editors on the web, Google Docs doesn't use contenteditable and instead uses its kix-editor. While moving the cursor on left/right presses is simple, how do they position their cursor when a user presses up or down?
For example, when a paragraph is multiple lines, how does the cursor know what is "above" it?
Or going up or down across multiple paragraphs, in a situation where there is an empty line between them and the cursor manages to save its horizontal positioning, despite the fact that the empty line forces it to move all the way to the left?
Looking at the DOM in Google Docs, it appears they do their own laying out. That is to say, they measure paragraph lengths and split them into separate divs. Therefore, the idea of iterating through the different ranges in the div "above" the currently selected div is a finite problem, instead of potentially an infinite one (if the previous paragraph is immensely long).
I'm putting the final touches on an application that Ive been working on for quite a while and while I understand how to restyle existing components by using inheritance Im coming up blank in my search on how to accomplish this last thing.
I want to apply a custom color/image behind the text or icon representing the current activity I am in. This would be similar to how the tabs have the highlight underneath them while selected. I am already using the tabs and have figured out how to change the image resource that is the little underline in the tab bar. Now I just need to accomplish the same look for the action items.
Ive overlooked the actionbarsherlock library for the past day and a half but I dont see anywhere that I could do what I want to accomplish. I have to imagine that such a thing can be done but like I said before so far Im coming up short. Any help would be much appreciated.
I figured out a simple way to do what I asked earlier. I just created a square shape in xml, put text over it, assigned it the gradient and color I wanted and assigned it to that action item I wanted highlighted in the activity i was in.
Yes, you read right - my UITextField has multiple lines for some reason and it is driving me crazy.
I have an app where users can edit content directly in a UITableViewCell. When they tap the cell, the text in the cell's label is put into a UITextField that is then added to the UITableViewCell. Once the UITextField hits a certain amount of characters (not sure exactly what the magic number is), it splits onto multiple lines and looks terrible - the first row is clear, but the second row is clipped by the bottom border of the UITextField.
I do not want to use a UITextView as I prefer the single line in my situation. Has anybody seen this behavior before? Is there a way to prevent it?
Oh, I am using iOS 4.1 as my base SDK.
Found it - the clipsToBounds property of the UITextField needs to be set to YES. If using Interface Builder, the "Clip Subviews" box needs to be checked.
