How to set scroll bar to right end by default in right to left reading rich edit control?

Hello, I am developing an application for Right to Left reading. I am inserting a file data into a rich edit control. When the data crosses width of a control, it introduces a horizontal scroll bar. But this scroll bar is put to left end instead of right end. I tried with some try outs as follows:

1)Changed rich edit styles for Right to Left reading & right aligned text.

2)Sent an explicit Scroll bar message, to set it at right extreme.

3)Retrieved scroll bar's info & set its position to Maximum. But none worked.

Is there any way to make it right aligned by default? Thanks in advance.

Should it be that your OS version does not support right-to-left layout?

Hello,
I am doing all this on WinXP Arabic, & it is supporting other applications like Notepad, a right-to-left layout.

Hi Sam,

Probably not the perfect solution but you may try this:

C++

//scroll to far right
m_RichCtrl.SendMessage(WM_HSCROLL, SB_RIGHT);
//scroll back 1 page
m_RichCtrl.SendMessage(WM_HSCROLL, SB_PAGELEFT);

Put this code at the end of OnInitDialog for example.

Olivier.

Hello Olivier,
Thanks for your suggestion. But this code works partially for some situations. In some cases it moves the scroll bar by page, such that the right side content is not shown(which should be shown in right to left reading case).

Could you provide a piece of code to reproduce this case? If I can reproduce it, maybe I can also find a workaround for it.

FillRichEdit() //this function is used to fill rich edit with // a file data
{
//Read data from a file
//Set it to rich edit through SetWindowText()
m_RichCtrl.SendMessage(WM_HSCROLL, SB_RIGHT);
m_RichCtrl.SendMessage(WM_HSCROLL, SB_PAGELEFT);
}

I use the same code and I don't have any problem. It probably comes from the content. Try without the file first. For example try with m_RichCtrl.SetWindowText("blabla").

Ok. Have you tried with Arabic/Hebrew language? It is having problem with that.

Olivier Levrey 23-Sep-14 5:57am

I tried with Arabic. It works.

I also tried with Arabic, but in some cases it gave problem as mentioned above. Have you inserted data such that last line will be more than rich edit width & will cause scroll bar to be shown?

Olivier Levrey 23-Sep-14 9:03am

Of course I inserted a long line otherwise I wouldn't call it "testing". Please provide the complete source code to reproduce your problem. I can't help further if I can't reproduce it.

The source code is simple and there is nothing more than file opening, reading & printing data in rich edit control.

OpenFile();
ReadFile();
//Create formatted_string.
m_RichCtrl.SetWindowText(formatted_string);
m_RichCtrl.SendMessage(WM_HSCROLL, SB_RIGHT);
m_RichCtrl.SendMessage(WM_HSCROLL, SB_PAGELEFT);
