GTWVG to Pritpal Bedi

[José M. C. Quintas]

Please check my commits for gtwvg.

Here a demo, and simple tests with another incomplete features.

button have the possibility to use text + icon, since windows vista, but
need adjust to it

loadimage() can resize image, since windows vista, but gtwvg do not have
this possibility and do not use it

wvgstatic() have the icon option, but do not have the option to define icon

and another things.

I create some static controls as test, or because can't do the same with
wvgStatic().

I do not know the standard names to send all these files as pull request.

On a first momment I think on create a "draft" folder on gtwvg/tests

Please check it.

I think the unique limitation on gtwvg to use windows controls on GT are
the controls that require focus, like EDIT (SLE/MLE).

Current wvg samples do not use any windows control on gt, and they are
easier to use than wvt* controls.

Check this on attached demo.

Note: rmchart sample need rmchart.dll but I think you have it.

Hi Jose, Just wondering if you took WVGTST  program set any further than the download above. 

I've compiled it and it doesn't have any mouse recognition, or [Tab] key 

Regards,

[José M. C. Quintas]

Many thanks for that Jose. I'll take a look at that.

In my post #2,  I was actually referring to your file wvgtst.zip that you added on #1 to Pritpal in this post.

[José M. C. Quintas]

Post is from april/2023, more than 2 years ago.

My current application is using multithread, GTWVG, FIVEWIN and HWGUI, all together on same EXE.

Can't add HMG 3, HMG Extended, OOHG, because there are functions/classes with same name as FIVEWIN.

Hi Jose,

I try to check you have add some gtwvg feature a GitHub project wvgtest (link: https://github.com/JoseQuintas/wvgtest) —
when compile/run its tests, the generated output (e.g. the image tests, including tests\tstall.png) doesn’t match the expected PNG (i.e. visual difference).

• Text drawn over a transparent background
• Images loaded from .rc (resource) files not display
• The image should stretch to the full button width/height
• All controls (buttons, labels, etc.) should render with transparent backgrounds

after compile with Harbour Buiild Version

Harbour 3.2.0dev (r2503251254)

Compiler: MinGW GNU C 7.3 (32-bit)

how to write a correct build / test (compile & run) and how to fix the discrepancy (so your output matches tstall.png).

Regards
Anupam

There are some pending pull request may be some things depends on these requests.

Some considerations:

manifest can change visual style, this begans on windows XP.

You can create a file name.exe.manifest or you can built-in the manifest on EXE.

LoadIcon() and LoadImage() on GTWVG does not resize image, this feature is available since Windows Vista, using extra parameters.

button with text + image, this is not available without manifest

tooltip is not available without manifest

and others visual styles

Important:

GTWVG on harbour 3.2 does not works at same way as harbour 3.4, about windows handles/pointers. On 3.2 it uses numbers.

Source code is to harbour 3.2 only.

You can download updated gtwvg from here

https://github.com/JoseQuintas/harbour32_fork/tree/master/contrib/gtwvg

And/or check changes on commits, I allways move my changes to top, after update harbour 3.2

https://github.com/JoseQuintas/harbour32_fork/commit/4f7517b04cb1fae862ee01d898e2476e77013bb8

about to  create gtwvg.ch and change gtwvg.hbc:

I am currently using GTWVG + FIVEWIN + HWGUI on same EXE.

previous gtwvg.hbc causes conflicts because adds headers of gtwvg to all files

with the changes, only gtwvg source code uses gtwvg headers

Hi Jose
Thanks for your reply

I’ll try to compile and run your committed changes on gtwvg and follow the instructions you’ve provided:
https://github.com/JoseQuintas/harbour32_fork/tree/master/contrib/gtwvg

[José M. C. Quintas]

attached my default exe.manifest

create a rc file with this:

#define RT_MANIFEST 24
#define APP_MANIFEST 1

APP_MANIFEST RT_MANIFEST "exe.manifest"

AppIcon          ICON     "youricon.ico"

compile together with application

hbmk2 test.prg test.rc gtwvg.hbc

You will see another visual for windows controls, including edit, button, progressbar, calendar, and others.

I have tried using exe.manifest, which adds some visual effects to the controls, but it does not make the control backgrounds transparent.

How can I achieve background transparency for controls when using exe.manifest?

Also, I want to minimize the main window when a WvgCrt() modal window is open. I tried sending a message to minimize the parent of oCrt when clicking a button, but it’s not working.

Here’s the code I used:

{|| Wvg_SendMessage( oCrt:oParent:getHWND(), WM_SYSCOMMAND, SC_MINIMIZE, 0 ) }

Is this the correct message to minimize the main window?

Regards,

Anupam

What means background transparency ?

default windows controls uses windows default.

On some controls, icon with background transparency uses transparency to it

On some controls, set background color

On button, no option to background color, it is windows default

About send message:

You can use oCrt:SendMessage( ... ) without hwnd

About minimize

It is not part of my common usage

On search I found WS_MINIMIZE, WC_MINIMIZE, WIN_WS_MINIMIZE, HB_GTI_MINIMIZED (hbgtinfo.ch)
