O_O
This is really nice.....

first why separate position and dimension ? core::recti can be use for it (but you can use protected variable from IGUIElement ex: AbsoluteRect)
second can you think rtt are most optimized ?
-create an rtt from size and ECF_A8R8G8B8
-set an boolean to true on calculateVisibleLine
-if this boolen is true update rtt and set it to false
-render rtt texture to position...
third i think irr::core::list are most optimized between array

juste think

Using position and dimension is just a choice we made,
but using the AbsoluteRect and setRelativePosition() might be better indeed. (Especially when implementing OnEvent() )
Using a RTT is a good idea!

thank, just an idea from my engine concept to optimize general gui componment but nice for other ...

Updated TextArea with RTT to improve the performance.
It boosted my test project from ~800 to ! 1400 FPS

Ovan thanks for the tip btw.

There is still a small bug when using fonts with alpha, but thats an Irrlicht issue.

See this topic: http://irrlicht.sourceforge.net/forum/v ... =7&t=45901

If your using an old version of this TextArea, update!

Here's wishing this forum had some kind of "thank" or "like" feature

cool project RdR!

I tried a workaround for get correct alpha fonts on RTT

http://irrlicht.sourceforge.net/forum/v ... =7&t=45901

This will work only for 1 layer of images. But is better than nothing for now. (so can't be used for the whole GUI). but now you can have fonts also with alpha channel using RTT

Added support for temporary lines.
Temporary lines will be removed automaticly when they are expired.

Code: Select all

 
u32 lifeTime = 5; // Lifetime of the line
Line* line = new Line(lifeTime);

Hello,

I have some error when I compile my project with this code (Irr v1.7.3):

Code: Select all

 
Text_Zone = new TextArea(GuiEnv,GuiEnv->getRootGUIElement());
Text_Zone->setDimension(irr::core::rect<irr::s32>(5,deskres.Height-65, 105,deskres.Height));
Text_Zone->setMaxLines(6);
Text_Zone->setAlignment(TextArea::LEFT);

Did I miss something ?

Do you have Line.h and Line.cpp in your project?
Did you change anything in in the TextArea.h or .cpp ?
Can you build the example in the download? (main.cpp)

Yes

No

RdR wrote:Can you build the example in the download? (main.cpp)

Yes and it run...
But you must change this line :

Code: Select all

TextArea* chatBox = new TextArea(Environment);

to :

Code: Select all

TextArea* chatBox = new TextArea(env,env->getRootGUIElement());

I think I have some build option that don't pass. I will see that.
Sorry for inconvenience,

hi,

in TextArea.cpp line 575 you have a memleak.
just delete this line.

Code: Select all

tempLine = new Line();

First of all thanks for this really nice piece of code

But i cant figure out why the background looks wrong (see picture)
Used this to fill my textarea

Code: Select all

    std::vector<Line*> lines;
 
    if((*currentObject)) 
    {
        Line* line = new Line();
        line->addString((*currentObject)->getName().c_str(), video::SColor(255, 255, 255, 255));
        lines.push_back(line);
    
        line = new Line();
        line->addString(L"", irr::video::SColor(255, 255, 255, 255));
        lines.push_back(line);
 
        line = new Line();
        line->addString((*currentObject)->getDescription().c_str(), video::SColor(255, 255, 255, 255));
        lines.push_back(line);
 
        line = new Line();
        line->addString(L"", irr::video::SColor(255, 255, 255, 255));
        lines.push_back(line);
 
        line = new Line();
        line->addString(doubleToString((*currentObject)->getPrice()).c_str(), video::SColor(255, 255, 255, 255));
        lines.push_back(line);
 
        objectPropBox->setLines(lines);
    }

Code: Select all

    // Create a new textarea
    const core::dimension2d<u32> screenSize = device->getVideoDriver()->getScreenSize();
 
    objectPropBox = new TextArea(GUIEnvironment, GUIEnvironment->getRootGUIElement(), GUI_ID_TEXT_AREA_OBJECT_PROP);
    objectPropBox->setMaxLines(8);
    objectPropBox->setAlignment(TextArea::LEFT);
    objectPropBox->setBackgroundColor(video::SColor(175, 0, 0, 0));
    objectPropBox->setPosition(irr::core::vector2di(screenSize.Width*0.7f, screenSize.Height*0.8f));
    objectPropBox->setDimension(400, 150);
