a) some hundred lines of code from childwin.pas to main.pas
b) redundant hints/captions/shortcuts/events for similar buttons/menuitems to their corresponding TAction in main.dfm .
This change
a) avoids several inconsistent captions like described in issue #595
b) makes it easier to have toolbars on the mainform which are controlled by childform.
- Consequently use Mainform.GetRegValue() to read these values, an overloaded method with either Boolean, String or Integer result. These methods keep a global TRegistry object (regMain) open while the application runs, rather than creating a new one for each caller.
- Remove Mainform.SaveRegValue() which was used in one or two callers. Rather use a TRegistry object and do that by hand. There's no significant advantage in using a SaveRegValue method currently.
* TNTGrid is not capable of displaying a sort arrow in column titles. So, signalize sort direction of columns in grids and listviews by lightgrey (= ascending) and mediumgrey (= descending)
* Remove special color for NULL cells in grids because it can conflict with the new sorting colors. Instead, place a grey (NULL) text in these cells. Less gaudy colors now.
* Also remove grey background in primary key columns for the benefit of sorting colors. PK cells have bold font anyway, should be noticable enough.
- File logging can be activated in preferences dialog, by default of course NOT active.
- One file per session is written to [Documents and settings]\[username]\Application data\HeidiSQL\Sessionlogs\
- Filename pattern: "[session name] [zeropadded session nr].log"
- Fetch more descriptive CSIDL_* constants for system folders from ShlObj unit rather than hardcoded hex values
- Consistency:
- Move all global preferences vars from mainform to childwin.
- Get rid of unused legacy vars NativeFieldTypes + LanguageOffset
- Readability:
- Add documentation
- Prefix preferences vars with "pref"
- Get rid of WITH .. DO statements
