Get Color, under the Cursor's character item ?

[paule32]

Hello,
like the Subject said: how can I get the Color Attributes under the Cursor - in a TEdit, TFileEdit derivated class ?

I found a partial Solution - So, implement a std::vector< TColorAttr > shadowCopy vector, that holds the Color Attributes of the Cells.

TEditor is simple: it only has two color palette entries (normal and selected text). So, in the original TEditor it's as simple as checking whether the cursor is inside the current text selection or not.

However, since you are attempting to do syntax highlighting with several more colors, the solution is not so simple. The view's rendered contents are usually stored in the buffer member variable, but it is not reliable to try getting information from there because it depends on the ofBuffered flag in options being set and on whether drawView() has been already called or not (because it could otherwise contain outdated information).

So, a possible reasonable solution for a more complex use case like yours is what you already did: to have a vector or some other data structure storing the styling information of each cell in the text.
