TRichmemo wheel speed
« on: May 03, 2018, 09:36:06 am »
Hi Everybody.

I am using the Trichmemo component in a project, and there is some behavior related with the wheel speed i can´t take control over.
I have compiled the project under several lazarus versions, 32 and 64 bit, and sometimes the speed of the wheel is fast, but in most cases the speed is low. But i do not modifiy nothing, it seems to be a default value that controls the wheel speed. (I mean, the number of lines in a TRichmemo that moves up or down when using the mouse wheel). 

¿Does anybody knows what is the variable or property that controls the speed of the wheel on Trichmemo component?

Thanks in advance.

Well, i must correct something in the last post.
I think the problem with the wheel speed on TRichmemo component it seems to be something related with the lazarus version. With version 1.6.4 the wheel goes fast, but with version 1.8.2 the wheel speed is low.

I don´t know exactly what could be the reason for this...

Regards.

I have the same problem with 1.8.2, and I have gone back to 1.6.4

There are other issues that have with 1.8.2, and they are with all applications, whether they are 32bit or 64bit. I don't have time to mess with anything that I don't know how to fix.

few questions.
1) is there a sample RTF? (related to the second question)

2) how's RichMemo scrolling works compared to Windows Wordpad on the same RTF?
