I've made the change and the background bitmap doesn't flicker at all, however, the controls ontop of the bitmap still flicker.
This is the change I've made:
KeyHandler now triggers OnEraseBkgnd instead of performing PatBlt
When the user presses a key, the key's number is stored in a private member variable of the Dialog.
To subsequently make it update the background image, the Dialogs' key handler performs :
OnEraseBkgnd now does the PatBlt of the static image behind the controls
Next, OnEraseBkgnd(CDC* pDC) is processed.
this handler first checks that a key was pressed, if so, it performs the targetDC.PatBlt (I just use the pDC that's passed in) then it returns TRUE.
If no key was pressed then I let this handler perform the default CDialog::OnEraseBkgnd(pDC)
After this change I noticed that the individual controls no longer need their RedrawWindow() called, however, they still flicker (but the background static image doesn't flicker at all now).
I've also removed the SetRedraw() calls
No the properties won't change, but I'm calling quite a lot of RedrawWindow methods for the controls on the Dialog and I'm noticing that the bigger the controls, and the more there are, the more flicker I'm seeing.
Can someone tell me how to display the "inifinity symbol" inside of a listview item. For example, i was just using Azureus (bit torrent client) and noticed that they used this symbol under its ETA column. How do i do this?
1. Font selection. They might have set the list ctrl font, or at least the font used when painting that part of the list ctrl, to a symbol font with an infinity symbol and then put ordinary text in the control corresponding to the charatcer number for the infinity symbol in the symbol font.
2. Overriding painting. They might have overriden aspects of the list control either using the custom draw, or owner draw approaches, probably custom draw and then be simply drawn the infinity symbol with a bit of GDI code, probably using a cached bitmap.
Search around for Custom Draw examples and Symbols fonts like WingDings. You'll have it cracked in no time.
Nothing is exactly what it seems but everything with seems can be unpicked.
