Allegro GUI isn't refreshing
Ceagon Xylas

My code is

1#include <allegro.h>
2#define _WINSOCKAPI_
3#include <winalleg.h>
4 
5char text_1[400]="Welcome to this gui thingy!\n\n";
6char edit_1[50];
7 
8//adds edit_1 to the end of text_1
9int ptext(void) {
10 ustrcat(text_1,"\n");
11 ustrcat(text_1,edit_1);
12 ustrcpy(edit_1,"");
13 return D_O_K;
14};
15 
16int func1(void) {
17 //alert goes here
18 return D_O_K;
19};

The problem is whenever...say...I type something into 'd_edit_proc' and press enter, I have to press another key or hover over the text box to tell it to update. By update I mean show that edit_1 is empty and that text_1 has been added to. How can I fix this?
Sorry for the bad explanation, but I'm not sure how else to explain it =/

I believe the problem is that your edit box captures the ENTER. Why don't you create your own edit box that, if you got an ENTER, raises it to the dialog?

Ceagon Xylas

Hmm... can you give me a more detailed explination of what creating my 'own edit box' would consist of?
Like what you mean exactly... This? 

while(!program_end) {
  textprintf(buffer,font,0,0,makecol(255,255,255),edit_1);
  //blit the buffer and stuff
}

Should I use the DIALOG_PLAYER stuff? Well, I guess I'd have to use my method above.

ReyBrujo

The easiest way is to make your ptext function return D_REDRAW_ALL instead of D_O_K. And, if the user presses ENTER in the edit box, to call ptext.

See here (I deleted a few lines because I am on Linux):

3char text_1[400]="Welcome to this gui thingy!\n\n";
4char edit_1[50];

6//adds edit_1 to the end of text_1
7int ptext(void) {
8 ustrcat(text_1,"\n");
9 ustrcat(text_1,edit_1);
10 ustrcpy(edit_1,"");
11 
12 return D_REDRAW_ALL;
13};
14 
15int func1(void) {
16 //alert goes here
17 return D_O_K;
18};

20DIALOG the_dialog[];
21 
22int d_myedit_proc(int msg, DIALOG *d, int c) {
23 if (msg == MSG_CHAR && (c >> 8) == KEY_ENTER) {
24 ptext();
25 return D_O_K;
26 }
27 else
28 return d_edit_proc(msg, d, c);
29}

A better solution should be to have ptext send a message to the textbox to redraw, so that there is only one redraw. But that is homework for you ;)

Oh wow! Thanks a whole lot! =D
