And yes under Delphi it does change the button's face color. We have used this in some of our multimedia applications. It's a limitation of Lazarus, not VCL or CLX. I am not sure what version of Delphi you are talking about, but at least under Delphi 7, Color is protected property of TControl which is not published by its descendants TColor -> TWinControl -> TButtonControl -> TButton. Forcing access to it via inheritance and setting Color property anyway has no effect -- I just checked. -- Alexander S.

There is no way to change a color of standard Windows button, except for system-wide change via Control Panel. Correspondingly, there is no TButton.Color property in Delphi. (See also http://msdn2.microsoft.com/en-us/library/ms673328.aspx#button_color_messages). The color actually used is available in Delphi as clBtnFace constant. Personally, I would say that this is ok, as it improves interface consistency. Instead of adding TButton.Color property, a descendant component (e.g. TColorButton or TCustomButton) should be implemented on all widgetsets. -- Alexander S.

Re: [lazarus] Object and Class declarations question

Object and Class declarations are very similar but, are they really the same? My concern is about smart linking. If I use Object instead of Class, will it takes less memory to smart link? I heard that Object is more close to a record than to a Class, is it true? The main difference is that objects of class types are always allocated on heap, so class-typed variables are essentially references. Object-typed variables can be allocated either statically, on the stack or on the heap. -- Alexander S.

Re: [lazarus] Code completion features missing or not ?
Ok. So GEXpert has a simple word search and not an identifier search. And this is wanted. Then the new functions will be called 'Find next word', 'Find previous word'. Ok? Perhaps "Find next word occurrence" or even "Find next occurrence of this word"? I am afraid 'Find next word' will be easily confused with the function performed by Ctrl+Right/Left. -- Alexander S.

[lazarus] [PATCH] Replace PairSplitter with Splitter in ObjectInspector
I am not sure what PairSplitter is for, and what are its essential differences from normal splitter (apart from slightly different API and the fact that it apparently does not work on Windows). Anyway, I noticed TODO item at the start of ObjectInspector.pp and decided to fulfill it instead of figuring out what's the deal wil PairSplitter. The attached patch is tested on Windows XP. -- Alexander S. Klenin Insight Experts Ltd. obj_insp_splitter.patch Description: Binary data
Re: [lazarus] SynEdit + Unihighlighter (must have fixed caps problem)
On 7/23/06, Mattias Gaertner <[EMAIL PROTECTED]> wrote: > I have recently started poking around it and have some ideas ;-) What ideas? Well, for starters, the code obviously will benefit from some refactoring. E.g. "mouse links" processing is spread over many different places, with some literally duplicating code. The interface of syntax highlighters needs improvement also. I tried to disable "mouselinks" over keywords and numbers (because clicking them will always lead to error). I have found the following: one the one hand, "IsKeyword" function defined in basic class is not implemented in descendants, on the other hand, "GetToken" function, seemingly designed to return the type of the current token, returns unadorned integer, with no way to interpret it, and GetTokenID function, which does return enumerated type, is pascal-specific. Is the above worth fixing? -- Alexander S.
