Hide button

[Fabien Comte]

Hello, 

I want to hide a button before animate another one.

That doesn't work (strange colors at old position):

gwinSetVisible(ghPushbutton1, FALSE);
GWidgetObject * temp_control = ((GWidgetObject *) ghPushbutton1);
gdispGFillArea(temp_control->g.display, temp_control->g.x - border, temp_control->g.y - border, temp_control->g.width + 2 * border, temp_control->g.height + 2 * border, GFX_BLACK);

That works (hidden but can be clicked):

GWidgetObject * temp_control = ((GWidgetObject *) ghPushbutton1);
gdispGFillArea(temp_control->g.display, temp_control->g.x - border, temp_control->g.y - border, temp_control->g.width + 2 * border, temp_control->g.height + 2 * border, GFX_BLACK);

It looks like if set invisible launched a background task.

Do I missed something ?

i replaced 

gwinSetVisible(ghPushbutton1, FALSE);

with

ghPushbutton1->flags = ghPushbutton1->flags & ~GWIN_FLG_SYSVISIBLE;

and it works

Can you post a screenshot that shows the problem?

Also, there are the high-level calls gwinHide() and gwinShow() which you should use. gwinSetVisible() is fine too though, but check the last parameter.
You should definitely not manually touch the flags.

Hello,

It's more complex that i imaginated. I tried to move on GWIN_REDRAW_IMMEDIATE = GFX_ON but gwinHide(ghMyPageContainer1); is never goes out. Do i missed something ?

Ok i found about the lock, my mistake sorry.

If you are directly drawing using GDISP calls, or manipulating GWIN flags directly, or having to understand the drawing lock then you are definitely approaching the problem incorrectly.

Ok i found, there was a timer that sometimes was fighting against me. I moved to immediate configuration and i was able to do everything i wanted.

Thank you all people for your help.
