Hi,

I have now used SetValue(). Its working. And regarding the ActivateL() : i havent used them but still its working.But like you said that it
may give problms for others so have included it.

Thks.

Add ActivateL()

... and you should add a call to ActivateL() for the slider.

It's funny how many people I have seen here, over the time, that forget to call ActivateL(). For some controls, that call does not matter, whereas for others it's absolutely essential for proper functioning.

Well SetMinValue sets the minimum value, not the current value - what did you expect?

Re: How to set fonts to a portion of a text in a list ?

I don't think that's possible.

I would say for something like that it would be necessary to take over completely the drawing of the cell with this formatting, and I don't know of any way of how to do this with CQikListBox.

Surprisingly this was quite easy on UIQ2, with custom item drawers: Get a rectangle, draw whatever you want into the cell. Very easy, very flexible. The only problem to solve is how to know what to draw into which cell because maybe it's difficult for the model to hold that particular data. All I know about UIQ3 is that you can mess around somewhat with custom text drawers:

Not so easy, not very flexible, and can get quite messy. Try, e.g. another font, and you mess up your listbox pretty quick!

Hi Praveen,

what do you mean by that.
do you want to Hide ScrollBar dynamically?
or have you kept this code in Constructor of your container?
checkout CEikScrollBarFrame class for more info.

Hi Praveen,

you can do it like this:-

CEikScrollBarFrame* ScrollBarFrame;
ScrollBarFrame->SetScrollBarVisibilityL(CEikScrollBarFrame::EOff,CEikScrollBarFrame::EOff);

You mainly need to have a basic undestanding of how a Symbian UI should be constructed.
Take the time to read a book, take some documentation here, on Nokia/UIQ/Symbian web site, take a look at the example in your SDK.

If you don't delete, you get a nasty memory leak.

Well, if you just want a combobox "to look at" but where the user cannot do something with it, you still could create it in the conventional way at view init and then use SetFocusing(EFalse). If the user cannot activate the combobox, it should just sit there and do nothing.

Wow, that's pretty weird what you try there.

A small wonder that this does not crash. Anyway, the combobox only lives a fraction of a second or so, because you immediately destroy it again; no wonder you see nothing: If has not time to draw itself before you already zap it. (If you see a button or an edwin in this strange way, it's probably only because this scheme somehow prevents the re-drawing of the background after the control is deleted.)

Please tell what you want to achieve. If you want a combobox in a view, don't create it in Draw() and immediately destroy it again, just create it within the view init and let it draw itself.

Use CQikViewDialog instead of CQikSimpleDialog.

Re: CCoeControl and Color

rbrunner — Sat, 06 Sep 2008 11:49:16 +0200

I played around with this as well and got the impression that the UIQ3 developpers were so busy making sure that theming always works that they neglected the basic ability of the controls to take color commands programmatically. I don't remember exactly, but I think there are controls that insist on theming and don't budge at all if you try to set color, by using CCoeControl::OverrideColorL() or similar.

I think the message more or less is "UIQ3 uses theming, period. Get over it."

It's not only color, anyway. CQikListBox works heavily with transparency and thus not only with background colors but also with background color gradients and background pictures.

Maybe some things look awkward, but maybe then that's just a deficiency of the theme(s) that you use for testing, and not a fundamental problem per se.

I found it also dangerous to work "against" themes somehow by setting my own colors. How many themes do I have to test until I can be quite sure that my own colors look reasonably good on any theme out there, even the weird ones?

Re: CEikScrollBarFrame Usage

arddev — Sat, 06 Sep 2008 10:55:28 +0200

Hi Brunner,

I managed to implement scrolling using CEikScrollbarFrame exclusively. Yes, I had to do all the things that you said I ought to if I were to use CEikScrollbarFrame. From properly positioning the scrollbar thumb, adjusting the scroll span and redrawing the controls with new content; all had be done manually.

Thank you for your advise that helped in knowing what it really means to use a CEikScrollbarFrame instead of CQikScrollableContainer.
