How do I get parameters for GetTextSize [message #43275]

I need to resize a DropList according to the longest string in the list.

How do I get the parameters for GetTextSize() (presumably something like Draw object and font)?

Thanks.

Hi awksed,

You could get your text width using GetTextSize(const FontInfo& ft,WString& str) and adapt the DropList width using DropList::SetMinSize(Size sz).

Hope this could be helpful

Cheers Smile

Hi BioBytes,

Thank you for your reply.

Sorry if my question was a little fuzzy.

What I really wanted to know is how do I obtain the actual font used in the DropList in question. (I assume this can be set to a different font from the standard font).

My code for the present is:

void MyDialog::MyFunction()
{
Font font = GetStdFont();
}

Presumably as this is called from the dialog it will not return the font used in the DropList if this has been changed. (DropList::GetStdFont() does not exist).

Regards,

awksed

Hi Awksed,

Ok that is somewhat clearer now. Perhaps you could try the code below:

#include <CtrlLib/CtrlLib.h>

using namespace Upp;

GUI_APP_MAIN
{
	DropList dl;
	TopWindow win;
	win.SetRect(0, 0, 400, 50);
	win.Add(dl.HSizePos(4, 4).TopPos(10, Ctrl::STDSIZE));
	dl.Add(0, AttrText("This is bold")SetFont(Courier(25)).Bold());
	dl.Add(1, AttrText("This is red").SetFont(Arial(25)).Ink(Red()));
	dl.Add(2, AttrText("This is centered").SetFont(Tahoma(25)).Center());
	dl.SetLineCy(30);
	dl <<= 0;
	win.Run();
}

Hope this could help you Nod

Good coding

Hi Biobytes,

Thank you. That is most informative.

Having set the font for the DropList item, how would I retrieve it.

Hi Biobytes,

Sorry. I must be rather dense but I cannot see where in the link you provide there is a clue as to how answer the following question:-

Given:

DropList dl;

dl.Add(0, AttrText("This is bold")SetFont(Courier(25)).Bold());

Font font = ???

// Please replace the ??? with the appropriate code to obtain the Font object that is set in dl[0] above (which would be the appropriate Font object to pass to GetTextSize(..., font) for dl[0]).

Regards,

awksed

Hi Awksed,

Sorry not having fully understood your second question Confused

I am not sure that getting the font of a line in the droplist could be done easily. AttrText does not have any corresponding function. You save the font name used in each line of the droplist in a Vector object.
