[Lazarus] Double click is needed to select/deselect item's checkbox in listview with checkboxes
Hello I made some tests about issue 13932 http://bugs.freepascal.org/view.php?id=13932 - Windows XP - everything works ok - Windows Vista 32bit Home Premium - I need 2 or sometimes 4 clicks to change checkboxes state Can anyone acknowledge?

Yes, I can reproduce this here (under Vista).

You are right, I tested with another mouse, only double clicks needed to change checkboxes state. Hardware problem with 4 clicks :) Dnia 05-11-2009 o 21:13:21 Martin laza...@mfriebe.de napisał(a): Yes, I can reproduce this here (under Vista).

You should distinguish between updating text and navigation. Tab *characters* are inserted into the text, while the tab *key* is used to navigate in special document GUIs, with distinct fields. The text in an editor is not organized into fields, so that the tab key here can be used as it was before other GUIs have been invented.

So what did you mean, what are your ideas of folding?
There are many possibilities, but most of them will be supported by very
few editors, if any at all.
A few ideas I had, but not all worth doing:
- language specific folds (begin/end or open/close tags in xml) =
existing for pascal
- temporary folds: not bound to any content. They exist as long as the
editor is open, (and would be a poor substitute for having 2 windows of
the same content)
They would work, by selecting any amount of lines, and fold them
- folding any paragraph, (defined by at least one empty line in-between
- folding by level of indent
- folding by special comments (as you indicated ///) but that again is
very editor specific. it is just a shorter notion of region.
It could be configurable by specifing the pattern / and it has the
advance of an automatic end at the next section / and they could be
leveled (///, , /, ...)
The /// are what you mentioned in your post. But (with the exception
maybe of overhead) it has the same properties as region:
- it is bound to an special editor
(or a set of a few special editors)
- it is imposed on every user
(if it is not treated as editor specific directive it is a comment; so
is {%region ...} )
- it must be maintained manually
(except for the end of each block is found automatically, sometimes an
advantage, sometimes a disadvantage)

Inside the IDE OnPaste is going to be used by codetools, but in user apps the programmer is free to use (and of course abuse) this on his/her terms. Codetools does not need to know every edit/modification of the text. In fact there are many edits/modifications that this part of codetool should not react to. Clipboard interaction (for an editor component) is a generic event that mat be of interest, in the same way as OnClick is on a button. - Internally SynEdit has a small set of methods through which *all* modifications to text are done. Agreed one would have been enough. But it is the same distinction has having 2 methods [cut and copy] or one [CutCopy(DeleteSelection:Boolean)]. They do however not move the caret. This would have meant to add special params. After all not every text modification moves the caret. They do provide hooks, that are used by other editor feature to react to the changes. I am aware that you (IIRC) prefer a micro-controller scenario. But for various features it is IMHO better to use generic hooks. Example: No micro controller is/should be needed to update bookmarks (Except for the controlling element in the bookmark manager). The bookmark manager hooks into synedit, observes any text change, and adjusts all bookmarks. This is actually a pre-condition for having the same content in multiply editor windows. Each SynEdit (using the same shared TextBuffer) can hook into the textbuffer and adjust to any change that happens. A single Replace(start, delta, text) method Can not deal (unless given a specialized argument) with the differentiation between smNormal and smColum. smColumn is very specific to Block-Selection and therefore translated there. the basic text modification only knows contineus/flowing text that can be edited/replaced. This again makes it a difference to an OnPaste event, which exposes the speciality of smColumn. something that does not exist in other edit actions.

Right :-( Eventually the new Version of FPC will be used, and eventually all code has to be able to be compiled with it I have several suggestions: - apply the new rules only in $mode Delphi - use an (global) switch to treat Inc/Dec as macros or operators - introduce new Incr/Decr macros, to reduce required editing of legacy code For the moment though, you are right. I can not really complain if it doesn't work for me, simple because I use an unreleased fpc version.

Re: [Lazarus] Auto indentation
And that's something *I* don't like. You never know which END belongs to wheach BEGIN. I always column align all ENDs to their corresponding BEGINs. You missed the second part of my argumentation. I'm thinking in the superior Modula syntax, that does not require begin-end pairs around statement sequences. I am not sure why you mention the Modula syntax. I thought we are talking about Pascal here. And Pascal requires the begin-end pairs (unless it is a single statement). And there is a logic behind it. I always see directly which block is related to the IF (WHILE, REPEAT, ...) statement: - if a then begin xx; yy; zz; end; a; b; c; - - if a then xx; a; b; c; - And if the statement or block is very short I can put the whole on one line: - if a then begin xx yy zz end; a; b; c; - - if a then xx; a; b; c; - I *never* put deeper level commands/blocks on the same column (including BEGIN/END) and I *always* align the BEGIN/ENDs. The BEGIN/ENDs delimit the block and are part of it so IMO they should be treated the same as all other commands of the block and be aligned with them. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Absolutely necessary, otherwise you get nice spaghetti :-) The BEGIN/ENDs delimit the block and are part of it so IMO they should be treated the same as all other commands of the block and be aligned with them. On the other hand, I think of BEGIN/END as other commands are INSIDE begin/end block, so I align begin/end with previous if/while/for/procedure/function, and indent commands inside the block. As of one-lines like: if (a b) then a := b; I NEVER use them. They could take up less space, but it is very easy to overlook them when you read lot of code. Moreover, having inner command on the new line adds up to the consistency of your code. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

I disagree... If the editor doesn't support it, it is simply two extra

Also for Form Designers like the one in fpGUI Toolkit, where it writes
the form layout and design INSIDE the .pas file, the custom folding is
very handy, because it hides the code parts that are normally not
maintained by users.
The option of folding on {%region} tags is also user selectable, so if
