Consult the text has many segments, each segment has different color, how to output is better.-CodePudding

Such as " call ,
"May break between them, such as
" went up into the mountain shoot tigers ,
to sweet potatoes,
"
Use gdi + drawing, the effect is not very good, you have what advice

CodePudding user response:

CRichEditCtrl SetSelectionCharFormat

CodePudding user response:

Thank you for your reply, this is a way,
If by HDC handle, can have a direct way of drawing

CodePudding user response:

Every word with color, the output word by word,

CodePudding user response:

Output can be word by word, calculate the information such as the position of each character

CodePudding user response:

Don't have to calculate the rate of the position of each character ", "
But to change the Pen

CodePudding user response:

If the simple display, use normal window, through the DC output, output before use SetTextColor sets the text color (must use DC_PEN)
If you want to display complex and can edit, use CRichCtrl, content contains display format the text of the control parameters

But to change the Pen

Change the pen is no problem, how to do, such as the

" went up into the mountain shoot tigers ,
to dig the sweet potato"

CodePudding user response:

When two words such as "down", an inter-bank, draw the RECT etc. How to deal with

CodePudding user response:

If it is Chinese characters, width and height is the same, as long as once

CodePudding user response:

If the string is
" went up into the mountain shoot tigers , and dig sweet potato "
Window width is 7 characters

1. According to window width delimited string
The string into a
1: string " went up into the mountain shoot tigers ,
"2: the string " to dig the sweet potato "
2. According to the color segmentation again string
String into:
1-1: string " up
"1-2: string "shoot tigers,"
1-3: string "
"2-1: string " to
"String 2-2: "dig a sweet potato"
3. In order painted string

Well, understand upstairs. Thank you

Try single-line:

 
Void StepText (HDC HDC, the RECT * rc, char * STR)//text literally 
{
Int len=strlen (STR);//calculate the length of the string 
Int posx.//the current character position 
Int posy=rc - & gt; Top; 
The SIZE the SIZE;//store each character of wide high 
SetTextAlign (HDC, TA_UPDATECP | TA_LEFT | TA_TOP);//set automatically update text position 
While (len> 0) 
{
Posx=rc - & gt; left; 
MoveToEx (HDC, rc - & gt; Left, posy, NULL);//move to the beginning of a line 
While (len>=0) 
{
Int t; 
If ((STR [0]) & lt; T=0) 2;//character of Chinese and western to distinguish 
The else t=1; 
GetTextExtentPoint32 (HDC, STR, t, & amp; The size);//get characters wide high 
If (posx + size. Cx> Rc - & gt; Right) break;//if beyond the border 
Cx; posx +=the size.//update the current position 
TextOut (HDC, 0, 0, STR, t);//output characters 
STR +=t;//update the characters 
Len -=t;//update the character length 
If (len<=0) break;//if the finished output character 
} 
Posy +=size. Cy;//migration processing 
If (posy + size. Cy + size. (cy) & gt;=rc - & gt; Bottom)//the next line cannot write, for scrolling 
{
The RECT the RECT=* rc; 
The rect. Top +=size. Cy;//scrolling position 
ScrollDC (HDC, 0, - size. Cy, & amp; The rect, NULL, NULL, NULL); 
Posy -=size. Cy;//restore migration processing 
} 
} 
}

Note that SetTextAlign (HDC, TA_UPDATECP | TA_LEFT | TA_TOP);//set automatically update text position
And the TextOut (HDC 0, 0, , STR, t);//output characters
