It is very simple.

First define the control having the parent as the same window where the tab resides.

Then use the following method to add the control the the tab page.

Code: Select all

<WindowName>.<ControlName>.AddControl ( ControlName , nPagenumber , nRow , nCol )
East or West HMG is the Best.
South or North HMG is worth.
...the possibilities are endless.

hI!
I found a bug in BosTaurus BT_DrawTextEx function
I want to print centered text rotated by 90 deg.
But, when changing length of text , it's position is not centered in vertical axis, it's always always positioned at the begin row, bet column of text is changed.
I think it should be opaque

I prepared some code, maybe I'm wrong, but centering text is with bug.
Also, vertical orientation is bad.

Code: Select all

#include <hmg.ch>

*----------

function main

	DEFINE WINDOW F1 ;

		WIDTH 700 HEIGHT 700 ;
		TITLE 'Draw text sample' ;

		backcolor {225,255,255} ;
		ON PAINT DoTest()
        
		DEFINE MAIN MENU OF F1
			DEFINE POPUP "tEST"
				MENUITEM "Test" action NIL
			END POPUP
		END MENU
		
	END WINDOW
	
	CENTER WINDOW F1
	
	ON KEY ESCAPE OF F1 ACTION F1.RELEASE
	ACTIVATE WINDOW F1
return

Hello Marek,

Thanks for your sample :!:

Please replace in your header file BosTaurus.CH the following line
#define BT_TEXT_CENTER 6
with
#define BT_TEXT_CENTER 1
and try to start your sample with above modification :idea:

It should fix the text center alignment in the horizontal orientation.
Kind Regards,
Grigory Filatov
