Topic: General / Netsurf compiling problems

Hi. I have tried to build the Netsurf from sources. It was built with success when i set TARGET=framebuffer but when I tried riscos as target It failed with error: frontends/riscos/Makefile:10: * Unable to find library for: Cares (libcares). I tried to install libc-ares-dev with no success. Could you advise how it could be fixed? Thanks

Topic: General / Draw rectangle on screen

Many thanks. it worked. Where can I read about all these actions? I failed to find a description of them. At StrongHelp I see only the list of them.

Topic: General / Draw rectangle on screen

Hi. Is it possible to draw on screen a rectangle and then clear it so the picture under it is restored? I need it to display the dragging area over the screen.
I was trying to do that with colourtrans_set_gcol and os_plot functions. but what can i do is to clear it with white color, even if i set the color to transparent. Is it possible?
thanks

Topic: General / GIMP folder at autobuilder svn trunk

Hi. I see that at autobuilder repository there is gimp folder inside graphics. Do someone already working on porting gimp? Is there any chance that it would be finished? Who is working on this?

Topic: General / correct way to work with system sprites

Finally I have found a working way. For those who is interested too:

int len = colourtrans_generate_table_for_sprite(wimpspriteop_AREA, (osspriteop_id)spritename, os_CURRENT_MODE, colourtrans_CURRENT_PALETTE, 0, colourtrans_RETURN_WIDE_ENTRIES | colourtrans_GIVEN_SPRITE | colourtrans_RETURN_PALETTE_TABLE, NULL, NULL);
    osspriteop_trans_tab * lenptr = (osspriteop_trans_tab*)malloc(len);
    colourtrans_generate_table_for_sprite(wimpspriteop_AREA, (osspriteop_id)spritename, os_CURRENT_MODE, colourtrans_CURRENT_PALETTE, lenptr, colourtrans_RETURN_WIDE_ENTRIES| colourtrans_GIVEN_SPRITE | colourtrans_RETURN_PALETTE_TABLE, NULL, NULL); 
    
    wimpspriteop_put_sprite_scaled(spritename, 0, 0, 
        osspriteop_GIVEN_WIDE_ENTRIES | osspriteop_USE_MASK | osspriteop_USE_PALETTE, 
        NULL, lenptr);  

Topic: General / correct way to work with system sprites

Andy, I have tried that too. unfortunately it still displayed with wrong colors.
Start to hate that sprite apis. They are really strange and no good info with examples how to correct use them.

Topic: General / correct way to work with system sprites

I have tried different things but cant do the correct colors. here my code:

    int width, height, icon_mask;
    os_mode icon_mode;
    wimpspriteop_read_sprite_info(spritename, &width, &height, &icon_mask, &icon_mode);

debug_printf(“wimpspriteop_read_sprite_info width = %d”, width);
debug_printf(“wimpspriteop_read_sprite_info height = %d”, height);

debug_printf(“wimpspriteop_read_sprite_info mode = %d”, icon_mode);
int size;
os_mode pal_mode;
os_sprite_palette *palette;
wimpspriteop_read_palette_size(spritename, &size, &palette, &pal_mode);

debug_printf(“wimpspriteop_read_palette_size size = %d”, size);
debug_printf(“wimpspriteop_read_palette_size mode = %d”, pal_mode);

int total_size = sizeof(osspriteop_area) + sizeof(osspriteop_header) +
(width * height * 4) + 2048 + 256,
s0, s1, s2, s3;
osspriteop_area *area = (osspriteop_area *) malloc(total_size);

osspriteop_header sprheader = (osspriteop_header *)((char)area + 16);
osspriteop_create_sprite(osspriteop_NAME, area, “!newfileicon”, 0, width, height, (os_mode )mode);
osspriteop_switch_output_to_sprite(osspriteop_PTR, area, (osspriteop_id) sprheader, NULL, &s0, &s1, &s2, &s3);
int len = colourtrans_generate_table( icon_mode, (os_palette *)palette, os_CURRENT_MODE, colourtrans_CURRENT_PALETTE, 0, colourtrans_RETURN_WIDE_ENTRIES, NULL, NULL);
osspriteop_trans_tab * lenptr = (osspriteop_trans_tab*)malloc(len);
colourtrans_generate_table(icon_mode, (os_palette )palette, os_CURRENT_MODE, colourtrans_CURRENT_PALETTE, (osspriteop_trans_tab)lenptr, colourtrans_RETURN_WIDE_ENTRIES, NULL, NULL);
//    int len = colourtrans_generate_table_for_sprite(wimpspriteop_AREA, (osspriteop_id)spritename, os_CURRENT_MODE, colourtrans_CURRENT_PALETTE, 0, colourtrans_RETURN_WIDE_ENTRIES, NULL, NULL);

wimpspriteop_put_sprite_scaled(spritename, 0, 0, osspriteop_GIVEN_WIDE_ENTRIES, NULL, lenptr);
//    wimpspriteop_put_sprite_scaled(spritename, 0, 0, osspriteop_USE_MASK, NULL, lenptr);  

//    if (icon_mask) wimpspriteop_plot_mask_scaled(spritename, 0, 0, NULL);
osspriteop_unswitch_output (s0, s1, s2, s3);

some things that i was trying is commented. Basically i see the image but colors a wrong. but they are diffrent if i try USE_MASK or not

Topic: General / correct way to work with system sprites

I tried wimpspriteop_readspriteinfo and get width=34, height=34, mask=1, mode=21. looks correct I think. I am not sure only about mode. is it correct?
What should i do with mask?

No I don’t write to wimp sprite area

Topic: General / correct way to work with system sprites

At the moment i was able to render it with wimpspriteop_put_sprite_scaled but it has a problems with colours at the moment. I understand that i need to do the colour trans table but i cant get the info about sprite. wimpspriteop_select_sprite returns wrong data and wimpspriteop_get_sprite gives me error that wimp receives incorrect parameter at R0.
I tried that code:

    osspriteop_header *wimpsprheader = wimpspriteop_select_sprite(spritename);
    debug_printf("wimpspriteop_select_sprite size = %d", wimpsprheader->size);
    debug_printf("wimpspriteop_select_sprite name = %s", wimpsprheader->name);
    debug_printf("wimpspriteop_select_sprite width = %d", wimpsprheader->width);
    debug_printf("wimpspriteop_select_sprite height = %d", wimpsprheader->height);
    debug_printf("wimpspriteop_select_sprite left_bit = %d", wimpsprheader->left_bit);
    debug_printf("wimpspriteop_select_sprite right_bit = %d", wimpsprheader->right_bit);
    debug_printf("wimpspriteop_select_sprite image = %d", wimpsprheader->image);
    debug_printf("wimpspriteop_select_sprite mask = %d", wimpsprheader->mask);
    debug_printf("wimpspriteop_select_sprite mode = %d", wimpsprheader->mode);

Topic: General / correct way to work with system sprites

But I want to use in my program exact file icon types from system. I dont talk about icon for my program

Topic: General / correct way to work with system sprites

Hi. I am trying to do the following. I have a sprite created at memory. And I want to put there a system sprite with file type icon. What is the correct steps to do that?
I was trying to use different osspriteop_ functions to read or get or put any sprite like “file_XXX” but I always get error “Sprite does not exists” or “No memory is reserved for system sprite area”. I am using toolbox if it does matter.
Many thanks

Topic: General / Toolbox button set state

I set the button type to radio so wimp does it for me. it works perfect select/deselect. I just wanted to know how to set the initial state and then read it when needed. so now i know that i was correct that i need to use button_set_flags. I did not find info which bit to use. so now i know that i need to set bit 21. Thanks

Topic: General / Toolbox button set state

Hi. I have created a custom checkbox using toolbox like this:

It works fine when i run the app and this checkbox has 2 states checked and unchecked. But i cant find a way how to set its initial state. Is there a way to set it checked? Maybe i need to use button_set_flags but I cant find any info what we can set there.
Thanks

Topic: General / Not enough memory to create sprite

this code is works but only sometimes rare happen such errors.
sprheader is used only for debug logging. it is a pointers calcing and the result is the pointer to the header of the first sprite

Topic: General / Not enough memory to create sprite

Hi. our ChatCube app sometimes produce error 0×82: Not enough memory to create sprite. I cant find any info about it in docs and what to do with that and how to avoid.
Could someone give a tips or any thoughts what could be wrong?
here is the part of code which sometimes produce this error:

mode = (os_mode)0x7860C051;

unsigned total_size = sizeof(osspriteop_area) + sizeof(osspriteop_header) +
(width * height * 4) + 2048;
sprbuffer = (osspriteop_area*)malloc(total_size);

sprheader = (osspriteop_header *)(sprbuffer + 1);
sprbuffer→used = 16;
sprbuffer→sprite_count = 0;
osspriteop_create_sprite(osspriteop_NAME,sprbuffer,“sprite1”,0,width,height,mode);

Topic: General / handle double click mouse event

thanks for your answer. it works

Topic: General / handle double click mouse event

Hi. Is there any info how correct to track the double click mouse events? Unfortunately I cant find anything about it. I need to distinguish the single and double click on same window. but both wimp_CLICK_SELECT and wimp_DOUBLE_SELECT flags have the same value 4. And my both expressions works on single and double clicks. Is it possible? Thanks

Topic: Community Support / hourglass problems (ChatCube - Cloverleaf)

It is about 2-3 seconds between. I will try your tip. btw I see hourglass but no its percentage displaying before 18. That is most strange for me.

Topic: Community Support / hourglass problems (ChatCube - Cloverleaf)

Hello. I am trying to show the progress with hourglass percentage. And basically it works but have some troubles.
First i set percentage to 1 (tried 0 also) run some network code. then increase it and run another network code. and do it until 100%.
the problem is that I see hourglass without percent indicator until it pass few steps. Maybe i miss some requirements?
I have add some logging and see such a picture
set hourglass = 1
call network url 1
set hourglass = 9
call network url 2
set hourglass = 18 —> start to see hourglass percentage at this step
call network url 3
set hourglass = 27
….. and etc
I sure that there are no hourglass_off calls between. What could i miss?
Thanks

Topic: General / What is correct way to setup the window z-index?

For those who want to test the app can download it here https://riscoscloverleaf.com/downloads/

Topic: General / What is correct way to setup the window z-index?

I want to describe how it was done. This was created with toolbox. Here i put some screenshots with windows properties https://imgur.com/a/9h9rFNs.
The main window is a window with buttons and edit field placed at bottom. It has an internal top left toolbar attached. As toolbar I used a window with vertical scrollbar and a pane flag. Its properties i show at screenshots by the link above.
Also i resize the messages window(which is internal toolbar for main window) when content changes with the following function:

int set_window_new_extent_height(toolbox_o window_handler, int height) {
    os_box extent;
    window_get_extent(0,window_handler,&extent);
    
    wimp_w w = window_get_wimp_handle(0, window_handler);
    wimp_window_state state;
    state.w = w;
    wimp_get_window_state(&state);
    
    int current_height = state.visible.y1 - state.visible.y0;
    if (height < current_height) {
        height = current_height;
    }
    if (extent.ymax - extent.ymin != height) {
        extent.ymin = -height;
        extent.ymax = 0;
        window_set_extent(0,window_handler,&extent);
    }
    
    return height / 2; // I return height in pixels to use for sprite building to know the real size of the window.
}

Ideally i need to know the best and correct way how to make a window with the following layout: https://imgur.com/a/lzFQ0xt
where the A and B parts should have a custom redraw function and vertical scrollbar. and C part should contains a buttons and edit fields which are controlled by the system

Thanks

Topic: General / What is correct way to setup the window z-index?

Hello. I have a main window with few controls in it and also nested toolbar as window at top of it.
The problem is that when we move the window the other windows could overlap the part of main window. here you can see it https://imgur.com/AqN9Yih
What did i do wrong? any way to setup that all parts of window could have same z-index and work like single plain?
Thanks

Topic: General / Is it possible to change the visible position for toolbox external toolbar?

So do you mean guys that the only way is to make this window separate and have a pain to always update its coordinates when i am moving/close/open/etc main window?
