// NOTES:
|
|
//
|
|
// Here is a list of items that have been found while investigating richedit
|
|
// problems with different versions, but were never implemented because we didn't
|
|
// need them in the code. Hopefully, this list will expand so someone in the future
|
|
// will be able to use any and all info we have found regarding richedit versions
|
|
// where we didn't need to write a wrapper.
|
|
//
|
|
// 1- EM_GETCHARFORMAT passing in a false is suppose to return the default charformat
|
|
// for the richedit. This works on all versions, except v1. V1 returns a
|
|
// charformat with the mask set to 0.
|
|
//
|
|
// 2- TOM (Text Object Model) wasn't implemented in v1.
|
|
//
|
|
// 3- With richedit 1 and 2, the thumb doesn't show up in the scroll bar if the
|
|
// richedit isn't big enough to show a certain size. This is why the max
|
|
// number of rows for the multi-line richedits in the header is set to 4. For
|
|
// the default fonts, 3 rows aren't big enough to show the thumb.
|
|
//
|
|
// Add more if not handled in the functions below.
