Change the color of a label that is already made
Is this possible? The TextStyle of AbstractTextControl definition is read-only. The label does not seem to have any method to repaint.
At the moment I'm to create two identical labels and hiding one at first, then when I "change the color of the label" I hide my visible label and put my only invisible in the visible. I think that making two labels is probably unnecessarily expensive (even if it does not solve the problem). Can anyone think of a better way to do it?
You can inherit from Label. Then, you can call Label. textStyle () which returns a pointer to the bb::cascades:TextStyleDefinition. Then, you can call setColor() to set the color. It should work. I have never done this, but the UI components auto update even if changed in C++.

I have a number of bookmarks that are long and have misleading titles because I forgot to enter a shorter more concise name when I first set bookmark them. However, I can't find a way to rename the other bookmarks that deleting the current and bookmarking this time change the title to something I recognize.
For example I have bookmarked Ebuyer and in my bookmarks list it says, "laptops cheap, etc, etc." all I want is 'Ebuyer. I realize that I can delete this bookmark and save it again and this time change the name at the beginning.Right-click on the bookmark, click on 'Properties' new 'name' type click Save.

Change the size of a window that is already open
Hi all
Is anyway to change the size (800 x 480), a window that is already open? The following code opens the window:
HAPwindow2 = window () .new ("Haptek_player")
tRect = HAPwindow2.sourceRect
HAPwindow2.rect = HAPwindow2.sourceRect.offset (190,0) - d.left, d.top
HAPwindow2.open)
end
I know how to change the size of the video in the window (window("Haptek_player").movie.sprite (1) .rect = rect (0, 0, 800, 480)) but I don't know how to change the size of the window itself. Any ideas?Here's the answer:
on haplayer2
tRect = window("Haptek_player").sourceRect.offset (190,0)
If _player.windowPresent ("Haptek_player") then
Window ("Haptek_player"). Rect = tRect + rect (0,0,624,280) - left, top, right and bottom 400 165 - tRect.offset (190,0)
Window ("Haptek_player"). Movie.Sprite (1) .rect = rect (0, 0, 1024, 600)end if
end624 280 values come if you subtract the resolution you want to perform from the original window dimensions (in my case 400 x 320).

How can I change the colors of fonts that I add to my movies?
Hi all
I have a simple question. I have a loot of VHS tapes I've had since Adam was a boy. I've been working my way through them and their conversion into DVD. This is probably very different from what most people use the software for. I've been using iMovie HD until it was more compatible, then Final Cut Express.
Did not go for a while and decided that I should start using Final Cut Pro. After a few days of fiddling, I'm at the stage where I'm ready to try to make a film I did before (do not take risk). The only thing I can't work on is to know how to change the color of all fonts that I use. So far, all I can use is the color that comes with the model. I want to change because I use my own back grounds. A white font on a light background is a bit difficult to read.
It was not hard to get that I did. One of the most polite things said about it was when Apple released it it should have been called iMovie HD Pro. I do not disagree with that.
That's people, thanks for any help you can give. If there are textbooks that would be useful any suggestion would be appreciated.
See you soon,.

What I forgot last time. Do I have reason to assume that chapter markers are deferred to iDVD when the project is completed.

How can I change the color of the mixture without polydioxanone it?
If I have a simple mixture of two lines, and to change the color, I'm going to > objectives > mix > release of mixture and then change the color by selecting and changing the shade of the race. So, I have to redo the mix and eventually reapply the mixture settings. I'm generally uncertain of color combinations and working things by trial and error so sometimes, it's a lot of clicking. I know there is a keyboard shortcut for the release of mixture, but it's always a chore if you use a stylus or a mouse.
It's what lies beneath my question - is there a quick way to change the color of a vector that is part of a mixture?
Thank you
Martin
You need not leave the mix to change the color. Use of the
tool Direct Selection to select only one race at the beginning or at the end
the mixture, which will allow you to change the color and the mixture
updates automacly. You can also select the entire mixture and use
-LiveColor to change the color of each object that make the mixture in
only once.

Change the printer to an email you have already created on connected HP?
Whenever I re - install the drivers / software for my 7510 Photosmart all-in-one, as the time where to find a new PC or reinstall Windows, I have to go into HP connected on the web and 'add a device '. After that, it makes you choose an email address to assign to your printer. From what I see, you cannot use a printer e-mail address that you already created. And you cannot go back connected HP and change the email of your printer that you already created - it gives you a "taking" error (Well, of course it is taken - by me!)
See picture attached for clarification.
Of course, I tried to submit a request for assistance and sent an e-mail after that my product is out of warranty, I knew, but connected HP is relatively new and this seems to be a bug, unless I'm missing something.
Thanks for any info, someone has.
Sorry, found my response on another thread - except connected HP is referred to as ePrint...

Change the color of the point to a point on the page label
I have several page elements that have labels. My customer wants to change the default color of some of the labels of page elements be of different colours on the page so that they stand out. Can I do this? I can change the color of the data in the actual cell, but I can't change the color of the label.
Example:
ARTICLES: < given here >
I fill the < data here > with a column in a table. I can change that, but what they want to change me is the color of the type in the label ELEMENTS:
Could someone tell me please the process for this if possible.
Thank you
PattiPatti,
You can do this by adding some CSS where you have the point label.
Change the desired page element, goto label box, add the CSS label. For example,.
Item:
I hope this helps.

Apparently a bug in Thunderbird is changing the "To" address to the Red even if the recipient is in my address book. The address is displayed when I start typing the first few letters of the recipient, but the text turns red which is difficult for me to see. I want to continue to enter addresses that I always (first letter type or two) would be the simplest solution to change the color from red to something easier for me to read. I looked in the configuration editor but can't seem to find a key that is appropriate for the address field. Can anyone provide assistance?
Update to Thunderbird 38.0.1.

Hello, I want to make an outline of the text that I created. I started with a blue background. Then, I created a text and changed the color of gold. I then put on an image and used the clipping mask to show the image by the text. Problem is it gets rid of color and shows that the peak through the text. I wanted a draft of the text with the picture. Is this possible?
Thank you
