    Differences in displaying the tab character

    Thanks, but this solution not working with VTV. Possibly VTV not support change this parameter.

    Differences in displaying the tab character

    I have TMemo and TVirtualTreeView on my form. Both controls set the same font, Ubuntu Mono. The text in both controls is the same, contains one tab (#9, marked in memo). Why does TMemo display it differently (wide) and VTV differently (narrow)?

    Speed up TDataSet Lookups

    @Dany Marmur When you click on the picture, a larger version opens. But the main question in this post is whether DBGrid is able to show combo with data in the cached lookup field? When the lookup field is constructed traditionally, with a dictionary dataset, then of course the combo list in DBGrid is not empty.

    Speed up TDataSet Lookups

    @Dany Marmur I try this trick, it working, but I can't get values in lookup list of dbgrid. It's is impossible? What I'm doing wrong?

    Experience/opinions on FastMM5

    I've got a callstack in FastMM4 set to 25, because that's the value that didn't cut off my log.

    Adjustable with source change?

    Experience/opinions on FastMM5

    @Primož Gabrijelčič I know that, but changing sources to imho is not a configuration 🙂 It should be in the file FastMM4Options.inc

    Experience/opinions on FastMM5

    @Pierre le Riche How deep is the call stack in FastMM5 reports? In FastMM4 it was hardcoded to 11, I reported an issue to add a depth setting option, but it was not added.

    Fonts & ligatures

    Try to work with JS in the VSC editor, you will quickly change your mind.

    Fonts & ligatures

    It just handles, only in specific situations, so I asked if it could be switched on permanently. I discovered it by accident, it only works if the text is a commentary and only if there is some unicode character pasted in the same line, here unicode ENVELOPE.

    Fonts & ligatures

    Because the code looks better, neater and clearer. I use ligatures in VSC and I am a fan of them 🙂

    Fonts & ligatures

    Is it possible to enable full ligature support in Delphi code editor?

    Slow IDE

    Which drive? The system one in vm? The network one from the host? And how do you disable the cache?

    Slow IDE

    I'm working with Delphi on a VMware machine, where I have a disk (with sources) connected from the host via "Folders sharing" mechanism. It's not too fast, but it usually works well. Sometimes Delphi can slow down a lot, e.g. I click the dot after the name of an object and wait a long time for a list of methods. So I fired a process manager called Process Hacker. And I watched what happens when Delphi "hangs and thinks". Here's the PH screenshot: It turned out that during the hanging, the I/O rate increases very much. But the Disk and Network ratios are not increasing. What could this I/O be?
