QCodeEdit

[Usability]

If I click, then somewhere else shift click, I would expect a selection to appear between the two places. This is not working on my machine, which may be relevant to the rectangular selection issues.

[fullmetalcoder]

It doesn't for me. I get a regular selection. It gives you the complete lines that were diagonally dragged over.

That sounds perfect, its just I don't see it with the current svn checkout.

Apologies... I forgot committing the latest changes...

It gives me a trail of cursor mirrors. Is that the same thing?

It is. But your working copy lacks a restriction so the "trail" may not be as usable as it should...

I've finally dealt with the drag and drop issue and the code (for ALL these neat features) is at last available on SVN. Have fun!

[Usability]

That is definitely better. I get a rectangular selection now, provided I use ctrl-shift and drag the mouse gently down the screen. If I move the mouse too fast, it skips some lines. So my rectangular selection has gaps in it!

I noticed another thing about clicking the start of a block and shift clicking the end. The first time I try this after invocation, it works and I get the range selected. All subsequent attempts fail. Do you see this?

If this worked it would provide a workaround to the drag speed restriction.

Fixed. I also made dragging more consistent and natural : dragging back does not leave unwanted cursors/selection anymore

I noticed another thing about clicking the start of a block and shift clicking the end.

As far as I understand the code , this action shouldn't even have lead to a selection but I fixed this... I also added the possibility to column select without dragging : click somewhere and then click somewhere else while holding down shift and control.

The only downside of having such functionnalities is that I'll have to write a maual if I want users to take advantage of them... Anybody willing to help with this?

[Usability]

We have a working column editor now.

This is an impressive software component. You should be proud.

[Usability]

Here is a thought.
With your cursor mirrors, could you allow the cursor movement keys to operate on all the cursors?

I just wanted to add some characters to the end of a 100 or so lines of different length. It would have been really nice to drop a cursor mirror on all the lines, push the end of line key, and start typing.

Then you could do other useful edits with a column of cursors, for example left arrow back a few characters and insert something.

You would kill of the cursor mirrors and return to a single cursor with a mouse click.

[fullmetalcoder]

Here is a thought.
With your cursor mirrors, could you allow the cursor movement keys to operate on all the cursors?

I added the possiblity to move aligned cursors (including but not limited to column edit) as long as the "real" cursor remains on the same line. This moves support Shift-based selection so it is possible to turn a column edit into column selection or to extend a column selection through the keyboard.

I just wanted to add some characters to the end of a 100 or so lines of different length. It would have been really nice to drop a cursor mirror on all the lines, push the end of line key, and start typing.

Support for such "extended" key bindings is more controversial (and currently trickier to implement) for it would break column edit but I guess I can always add a workaround for the end of line key since I admit this one would be handy...

Edit : after reviewing the changes with a more critical eye it appeared to be less consistent than I expected so I instead implemented a proper full "cursor move mirroring". Mirrors disappear as soon as any cursor (real or mirror) leave the line it was on and the alignment can always be restored (as long as there are cursor mirrors of course...) thorugh the start key.

[fullmetalcoder]

After rectanguar cut/paste the only other important omission would be commenting in/out a block of text. You could convert to comment by prepending what ever the language template identified with context id="comment/single", and convert from comment by removing that.

This is important for languages like VHDL and TCL that only have the type of comment character stops at the end of the line.

Done.
As you suggested I selected the "comment/single" context (and the content of the first <start> tag so avoid putting regexp here...). The actions are accessible via Ctrl+D and Ctrl+Shift+D, as in Kwrite/Kate but also through the context menu (beware though... they operate on current line(s), not on the one to which mouse cursor points...).

Lots of errors in "qcodeedit-1.0".

What I did on windows (qt4.2)?
1. Unzipped the file
2. Loaded the example.pro
3. Loaded the qcodeedit.pro
4. Loaded the standalone.pro
5. made example.pro dependent on qcodeedit and standalone
6. Build
7. Lots of errors

To copy to clipboard, switch view to plain text mode 

Any idea??
I wonder how others are able to compile.

[elcuco]

This means that the UI files are generated by QtDesigner4.3, and are not compatible with Qt4.2.

You have to install Qt4.3 or fix the UI files by loading them into Qtdesigner4.2 and then saving them back. There will be some information loose (the margins etc), but it will be easy to fix.

[fullmetalcoder]

I wonder how others are able to compile.

They are using the code from SVN trunk... The code you downloaded is really old and hardly worth testing considering all the bugfixes and improvements that have been done since then...

[Usability]

Sure, its confusing with that obsolete qcodeedit directory sitting there.
The thing you need to know is that the working version of qcodeedit is the one inside Edyuk. You can get it like this:

svn checkout http://edyuk.svn.sourceforge.net/svnroot/edyuk/trunk/3rdparty/qcodeedit2

svn checkout http://edyuk.svn.sourceforge.net/svnroot/edyuk/trunk/3rdparty/qcodeedit2

We need a FAQ on this.

[Usability]

Is there any way of making the editor save its contents under a new name?

pEditor->setFileName(qsNewFileName);
pEditor->save();

Looked tempting, but setFileName is protected. This would seem like basic functionality I would expect to be able to do without subclassing.

The "protected" visibility of this method stems from early genesis of QCodeEdit when it was not yet fully separated from Edyuk and thus dependent on qmdilib... Fixed.

[Usability]

Sorted, thanks!

[vermarajeev]

Very confusing
I go to edyuk.svn.sourceforge.net/svnroot/edyuk/trunk/3rdparty/qcodeedit2 and then how do I download the code. I get a link
1. "Revision 365: /trunk/3rdparty"
2. Click on "codeedit2"
3. another tab appears.

Is there a way I can download the new version of codeedit?

Is there a reason you cannot just run the svn command I posed further up this page? That will create a qcodeedit2 directory containing all the source.
You do not need a login account or anything, which is something that surprised me the first time I did it.

This is all you need to download the editor, build the editor and its example program, and run the demo

svn checkout http://edyuk.svn.sourceforge.net/svnroot/edyuk/trunk/3rdparty/qcodeedit2
cd qcodeedit2
qmake 
make
example/example  lib/qcodeedit.cpp

svn checkout http://edyuk.svn.sourceforge.net/svnroot/edyuk/trunk/3rdparty/qcodeedit2
cd qcodeedit2
qmake 
make
example/example  lib/qcodeedit.cpp

I think the speed with which this editor is being developed means you have to get into svn.

The demo is no use as an editor, no save menu for example, its just there to show you how to call the editor from your own code. And its handy for logging bugs

[vermarajeev]

See the attached file.
I copy the path "http://edyuk.svn.sourceforge.net/svnroot/edyuk/trunk/3rdparty/qcodeedit2" in Mozilla and I get the page as shown in the image attached.

Go grab yourself a subversion client: http://subversion.tigris.org/ (svn-1.4.5-setup.exe is a good choice for Windows).

[Usability]

I get the page as shown in the image attached.

Thats the place. You want all of those files, directories, contents of the directories etc. Download them from the browser if you must.

Or there is always the single svn command.
