This is a U++ program (version 0.0.1 alpha) released for testing and comments.

Features implemented
1. Splash screen
2. About dialog
3. Menu and popup menu
4 Toolbar
5. Status bar
6. Options dialog
7. Help (using Topic++)
8. Editors dialog (only shows DocEdit and LineEdit)
9. use of .rc file to embed program icon and version info.

This program is meant as a simple template program which I will use to explore the various aspects of U++.

I'm still new to U++ so I would appreciate any ideas or suggestions on this simple template. I want to get it right so that later I will write an article that explains how this program works.

Thanks in advance
Yeoh

Hi Yeoh,

very nice work! It was helpful for me. I was still unaware of Topic and how to use it. U++ is a continue surprise for me. But now I filled the gap.
Please continue on this line, with very simple interaction among widgets... sorry, controls. When all normal controls are covered perhaps a simple application about sqlite would be greatly appreciated by our forum.
Many thanks,

Luigi

Comments:

I feel a little bit uneasy calling exploreEditors in constructor. In my book, that is not a very good practice, I would rather make it a separate call...

I would rather used TimeCallback for Splash - direct use of "timer ID" comes with danger of ID clash - there is even some "protocol" about enumerating these IDs to avoid this (see e.g. ToolBar). TimeCallback wastes a little space, but is easy to use.

"Ini" configuration format is OK, but least important. Usually, we use binary serialization for .cfg files (Serialize method, operator%) or CParser or Xml(ize).

P.S.:

I usually place more than single layout in .lay file, but this one is rather matter of personal preferences...

Hi Luigi,

Thanks for testing it. I'm glad it helps.
Yes, I will do one for SQLite.

Best Regards,
Yeoh

Hi Mirek,

Thank you very much for your comments. You're absolutely right about calling member function in constructors. I will put a "load" button in the lay file to call the function. Smile

Thanks. I will learn how to use TimeCallback.

U++ is great. It provides several ways for handling cfg files. I dislike registry. In future U++ apps, I will use the several methods you mentioned.

Best Regards,
Yeoh

P.S. Yes, I prefer to use one lay file for each class. My idea is to have 4 files in each class: cpp, h, lay and iml. If the class needs more than one layout, it will be in the lay file for that class. I suppose there is a U++ coding style somewhere in the documentation. I will search for it. Smile

to help you some with TimeCallback:

It is about letting a Label bling by using a TimeCallback

Hi,

This is the latest version of my simple U++ program.

It now covers all of the "most frequently used" controls as shown in the layout editor. This version only shows how to create the control and set, get values from the control. No fancy or complicated C++ code. Smile

Also, there is a custom USC file for UPX compression and file deletion.

Thanks and best regards,
Yeoh

P.S. This program was built using U++ 611-dev1 version and tested on Win2000 with MSC8 Optimal Build.

Obsolete attachment removed. Please see corrected version below.

Cool , thanks !

Nice work. On my system the window was positioned off screen at startup and I had to use the system menu to move it back on screen - i.e. Alt Space -> M -> use left arrow key to bring the window in view. Using Windows cascade or tile wouldn't bring the window in view for some reason. (Win XP).

I have a 20 inch widescreen LCD - 1680 by 1050 or something.

Hi Graeme,

Thanks for reporting. This is strange as I assumed the main window automatically centers itself on the screen with the correct Z order. You're right about this too. I noticed that sometimes when I run it from theIDE, it is "hidden". There must be a Z order problem somewhere.

I'll have to look into the U++ source to see what is really happening. Smile

Will post a revised version soon.

Best Regards,
Yeoh

What about simply looking at TopWindow docs? Smile

(OK, I know - it is unusual to have things documented in U++ Smile

(OTOH, right now, only undocumented basic widgets those in Static.h and ScrollBar.h).

I should have been more helpful and said it's only off-screen the first time or if I delete the config (.cfg) file. If the config file is present the app comes up in centre screen. Also the splash window is always centre screen.

Splash=0
SaveWinPos=0
PosX=0
PosY=0

I'll see what else I can find.

Looks like it's just that you don't initialize class members mainwposx_ posy if there's no config file.

Hi Yeoh,

I had tested your application under FreeBSD (it was winXP before) and I got an error, but I don't know what the reason is.

/home/masu/projects/upp/MyUppApp/MyUppApp.iml:4: error: expected unqualified-id before numeric constant


So I commented the affected line and it seems that it is not needed at all.

Hi Matthias,

Thanks for testing it under FreeBSD. Smile
Yes, you're right. The "Complex" image in MyUppApp.iml is now not used. MSC8 did not detect this! I must look at the compiler options again.

Fixed! Smile Corrected version now uploaded.

Yeoh
