The point is not to prove that it works or that it doesn't, but to find out when it works and when not.

That crashes when Foo = nil and Short-Circuit Boolean Evaluation is off.

As mentioned elsewhere, you need to show more code that is before the function. The function code is correct, it is something before it that makes the compiler unhappy.

As the error report mentions a missing radconsole subfolder in that URL, it may as well be an error in the sources affecting all target platforms.

AFAIK, the path to the database is configured in emsserver.ini

Sounds like this one: RSP-40290 - RAD Server Console DLL not working

Not according to the feature matrix:

The reason why FMX Linux is only available for Enterprise and Architect is, that those are the versions targeting Linux as a target platform. With a Professional version you can't compile code for Linux.

It has it when I connect from here: Perhaps it depends on the license and active subscription status. AFAIK, there is no other official way to download it than my.embarcadero.com.

I didn't say anything about X:

Make sure that the DLL can be found.

The CreateXX are class functions. Therefore they don't change LocalMatrix itself, but return a new matrix instead. I'm not sure if I understand you right, but it might be sufficient to set the RotationAngle of the StrokeCube according to the vector V between those two spheres. The Y value should get the angle (in degrees) in the X/Z plane, while the Z value should get the inclination angle to that plane (not tested).

When working with styles, the Color property of the form is ignored. Unless seClient is removed from its StyleElements property, the forms client space is controlled by the style.

A TCustomPanel is not filled with a color, but with part of the style bitmap (defined in the GroupBox.Frame object). In a lot of cases this may be similar to a solid color, but it can as well be some texture or even a transparent area for some styles like Amakrits. You might really get the best results with setting the labels Transparent property to True.

What type of control is the Parent of the label (TForm, TPanel,...)?

See here: Update: You can see what colors are returned here: function TUxThemeStyle.DoGetStyleColor(Color: TStyleColor): TColor; begin case Color of scBorder: Result := clWindowFrame; scButtonDisabled: Result := clBtnFace; scButtonFocused: Result := clBtnFace; scButtonHot: Result := clBtnFace; scButtonNormal: Result := clBtnFace; scButtonPressed: Result := clBtnFace; scCategoryButtons: Result := clBtnFace; scCategoryButtonsGradientBase: Result := $C0C0C0; scCategoryButtonsGradientEnd: Result := $F0F0F0; scCategoryPanelGroup: Result := clMedGray; scComboBox: Result := clWindow; scComboBoxDisabled: Result := clWindow; scEdit: Result := clWindow; scEditDisabled: Result := clWindow; scGrid: Result := clWindow; scGenericBackground: Result := clBtnFace; scGenericGradientEnd: Result := $C0C0C0; scGenericGradientBase: Result := $F0F0F0; scHintGradientBase: Result := clInfoBk; scHintGradientEnd: Result := clInfoBk; scListBox: Result := clWindow; scListBoxDisabled: Result := clWindow; scListView: Result := clWindow; scPanel: Result := clBtnFace; scPanelDisabled: Result := clBtnFace; scSplitter: Result := clWhite; scToolBarGradientBase: Result := $C0C0C0; scToolBarGradientEnd: Result := $F0F0F0; scTreeView: Result := clWindow; scWindow: Result := clBtnFace; else Result := clNone; end; end;

That depends on the definition of correct.

As I never use any dark theme myself I am thankfully not affected. Nevertheless, I would rather question the decision to make clBtnFace and clWindow looking quite similar in the dark theme, while they give a perfect contrast in the light theme.

I did some deeper investigation not concentrating on the colors itself and it turned out that HideSelection was True under some conditions. I fixed that in the latest beta. Can you please try and see if this helps a bit?

That would require to configure this color for all possible themes. The IDE comes with three, but works with any valid VCL style. The better approach would be to select a VCL style that matches your preference. This would even work without fiddling around with the MMX sources Another approach would be to file a feature request to change the standard themes color to something more visible. The problem with that is, that it is hard to show with a vanilla IDE installation.

Short answer: It doesn't use any color. The colors are intrinsic to a the selected IDE theme and not part of MMX. The difference you see in the selected colors are caused by comparing different controls. MMX uses a derived TListView for the members and TTreeView for the content, while the IDE uses a special VirtualTree version. Each have separate colors inside a theme. I'm not aware that TTreeView or TListView are used elsewhere in the IDE, which may explain why nobody complained about these colors up to now.

Looks here as expected:

There is no problem to have separate units for each form and still have them work together for whatever they are supposed to do. It is just difficult to give general advice instead of answering questions about a concrete problem. Things that come to mind: Use a data unit (TDataModule or a plain unit) to group the file access at one place. Restrict the forms to the UI stuff and call the data unit classes or methods as appropriate. Ideally, each for unit only uses the data unit. I'm pretty sure there are ways to accomplish that.

No, you should use separate units for each form and keep the {$R *.dfm} directive in each. The * makes it match with the unit name and the IDE will keep unit and form file names in synch. Please refrain from packing multiple forms into one unit. Otherwise you will most likely flood this forum with questions about the problems you get, while the correct answer will always be: Don't do that!

You can have multiple forms open in the IDE, each in its own unit. If you want multiple designers for each form, you need to create separate edit windows with New Edit Window. The usual way is to have a separate unit (pas and dfm) for each form. There are rare cases where declaring one or more form descendants in the same unit without the ability to design can make sense.
