Next moves

I'm kind of tired and bored fixing things for the Text class. Many display problems remain. The most annoying one is a "bug" with the MLM_QUERYLINECOUNT message. For some reason it returns difenrent values sometimes.

Now I want to move on. First register the unsolve bugs and then begin the work on the tree and table classes. Probably that will take me a couple of months at least. After that ProgressBar and Sash classes should be implemented.

Work on the port of the Program class should finish the loader for Eclipse and then a full compilation should be the last item in the list.

Well, that's the plan. Let see how close I follow.

Slowing down

There has been some slowing down on the updates, mainly because I have a heavier load of work and there has been more problems than anticipated with the Text class. I have added two tabs from the control example. One deals with the different kind of dialogs available from SWT and the other with the Text and StyledText classes.
StyledText class does not compile because of the dependencies with some classes that need to be ported so I left it out of the example.

As of now I continue to improve the text class getting ready of small glitches.

Habemus icons

After some extra,,,, extra,,, extra effort I "solved" the issue of the missing images in the Label class. Still needs testing, but so far it looks fine.

The problem is a bug in the WinCreatePointerIndirect that ignores the mini icons. The solution was to draw the image using the GPI Api in the WM_PAINT of the Label class. I used the code from the Botton class that implemented the same solution.

I decided to allow the WinCreatePointerIndirect to work for regular size icons. There is a pallete problem there and the will be problems when the image is 32x32 and the resolution calls for the use of 40x40 icons. In that case PM will scale the icon and it will look ugly.

I'll clean up the code and will upload the changes this week.

Fixing more things

As I go over the code I keep discovering new improvements and unimplemented features to work on.
Last week I corrected the default sizing of the Scale and Slider classes. Now the ControlExample shows them in a correct default size.
The one fix that was really important was the redrawing of the group class. This caused a mess everytime a control was redraw.

The problem happened because the original Win32 implementation uses some flags that indicate when the background should be restore. This feature does not exist in OS/2 so the solution was to implement the WM_PAINT in the group control and there take care of the background refresh. So far it works and now the groups refresh themselfs just fine in the ControlExample testcase.

Over the weekend I added support for the Innotek Font Engine. I tried to see if things worked. Unfortunally there was a lot of tweaking on the SWT port font code to circunvent PM bugs.
Clearly I need to go over the font code since using the FT2LIB screws the true type drawing. The change shows potential but needs some work. I left the engine turned off for now.

This week I'll try to fix the static control. It's now showing images. If I get brave I'll also try to subclass the WC_STATIC and create the conditions and tools to easily extent controls through this OS/2 feature.

Improvements

Last week I worked on solving many issues that are pending of solution. Looking at the ControlExample I solved issues with the List class. Many of the display problems were taken care of. Now the code seems to show the List exactly as the Window version does, except for the vertical scrollbar that in OS/2 is always visible.

I also solved some other minor issues like the color of the tabs in tabfolder and I began the imlementation of clipboard support in the Text class.

Also today I fixed the font dialog exception and now the font can be selected for any of the controls.

Clipping away

It took me a long time to discover why the composite classes didn't repaint their backgrounds after being clipped. At the end thes solution was so simple that's not even funny.

Well with that problem left behind, I have a whole lot of more things to do. First I will go over the implementation of menus. So far everything seems to work OK. I added the mnemonics and they work just fine.

I dicovered a new bug on the creation of the acceletators table. I going through the C JNI implementation.There seems to be a problem. I'm also looking into adding the icons to the menus and the implmentation of the progress bar using the slider control.

The easy part is to finish the mouse events (at least of the second button).

Well, let's go back to work now.

More bugs

As I advance on the task of making the control example work, I keep coming accross new bugs. Now I discover that some controls inside the notebook page, do not update their state correctly, but I'll leave that problem for later.
Right now I'm learning how to capture the mouse events inside the notebook pages. I also fixed a crash produced by right mouse button being clicked inside the notebook window.

My work will slow down a little the next weeks for personal reasons.
