Re: [Lazarus] IDE Font

Okay, after some research I found an easy way to fix the problem. I thought this might be useful to others. You can easily define your own styles and change theme for Gtk2. Just create a files called ~/.gtkrc-2.0 and put whatever settings you prefer into it. For example to change the default font

Re: [Lazarus] IDE Font

Mattias, when I changed the Raspbian fonts (specifically the sizes) using the Raspbian tools the IDE font sizes do not reflect that change. I tried rebooting and the Lazarus fonts sizes are unchanged. I rebuilt Lazarus and the font sizes are unchanged. --

UTF8Delete probably takes an AnsiString (or String) as var parameter and for var parameters the static codepages have to match exactly (String has CP_ACP while Utf8String has CP_UTF8).   Just please help me understanding this: The unit LazUTF8 unit is for manipulating UTF8 strings only,

Can someone tell me before I create a fix, does there exist something inside Lazarus to change the font of the controls which make up the Lazarus IDE? Purpose: I lowered the desktop resolution in Raspbian from 1920x1080 to 1366x768. Unfortunately at that smaller size the fonts being used by
