canvas - Flex 3 - Custom tab navigator -


I'm trying to create a custom tab navigator to look like.

In addition, when there is a rollover, the borders of the arrow should be in blue (as the label in the current tab).

For that purpose, I have a custom component: a hbox that contains a label and a canvas with 3 images (depending on the current state of the arrow is to be changed for the tip). Then, I thought of overlapping the components to get the blue highlight color (ex: arrow arrow 3 arrow arrow arrow 4. In the Button 3 the image of the arrow tip will be transparent outside the arrow, so that we can see that the following button Black color).

Now I am trying to replace the components inside the canvas ... but I can not. After the creation is complete, I provide the label text and I was computing the coordinates of the component but it does not take into account the width of the label ... -_- '

Any thoughts?

Thank you regards,

read on . You must be updated; Positioning and shaping your child's components in the UpdateDisplayList () method; Not in a composition. Full handler

You should either label the text in making a commitment or label when you know what it is.

If you want to share some code, we will be able to improve the exact problem. If you run the code like this: 

  myLabel.text = 'Blabblabblahah'; Trace (myLabel.width);

I hope that the width has not been changed to reflect the new text because myLabel has not yet run through its component lifecycle.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
