Hi Arni,
I am not sure, wether i am right or not nor wether it is the best way to do it.
I would derive a class from Label and reimplement the Paint Method of StaticText
void StaticText::Paint(Draw& w)
{
Size sz = GetSize();
if(!IsTransparent())
w.DrawRect(0,0,sz.cx,sz.cy,SColorFace);
PaintLabel(w,0,0,sz.cx,sz.cy,!IsShowEnabled(),false,false,VisibleAccessKeys());
}
to
void StaticText::Paint(Draw& w)
{
Size sz = GetSize();
if(!IsTransparent())
w.DrawRect(0,0,sz.cx,sz.cy,BackgroundColor);
PaintLabel(w,0,0,sz.cx,sz.cy,!IsShowEnabled(),false,false,VisibleAccessKeys());
}
and add "Color BackgroundColor" and the get/set-Method to your derived Class
to get it blinking create a Callback-Function, that changes your Backgroundcolor and let it be called each n ms by setting up a TimeCallback with Ctrl::SetTimeCallback(int delay_ms, Callback cb, int id)
hope that helps and isnt too bad,
Bas

your welcome!
for all of you who need some code:
header:
class BlinkingLabel : public Label {
private:
Color BackgroundColor[2];
int currentColor;
public:
BlinkingLabel();
void blink();
virtual void Paint(Draw& w);
};
source:
BlinkingLabel::BlinkingLabel() {
currentColor=0;
//the two Backgrounds between wich is switched
BackgroundColor[0] = Color(255,0,0) //red
BackgroundColor[1] = Color(255,255,255) //white
SetTimeCallback(1000,callback(this,&BlinkingLabel::blink)); //start blinking every second
};
void BlinkingLabel::Paint(Draw& w) {
Size sz = GetSize();
if(!IsTransparent())
w.DrawRect(0,0,sz.cx,sz.cy,BackgroundColor[currentColor]);
PaintLabel(w,0,0,sz.cx,sz.cy,!IsShowEnabled(),false,false,VisibleAccessKeys());
};
void BlinkingLabel::blink() {
currentColor=1 & ++currentColor; //toggle between 0 and 1
Refresh();
SetTimeCallback(1000,callback(this,&BlinkingLabel::blink)); //continue blinking every second
};
and the main:
...
BlinkingLabel bl;
bl.Transparent(false); //so we arent transparent and our background will be seen
bl.SetText("my background ist switching every second between red and white!");
...
*EDIT: The Error, wich Luigi posted was removed in the Code
have fun

Hello,
thank you for the nice code. I post here your example ready to run. Please note that one line was not recognised by the compiler. I commented it and it works the same. Please check if it is necessary. Moreover the text on the label doesn't appear.
Luigi
#include <CtrlLib/CtrlLib.h>
class BlinkingLabel : public Label {
private:
int currentColor;
Color BackgroundColor[2];
public:
BlinkingLabel();
void blink();
virtual void Paint(Draw& w);
};
BlinkingLabel::BlinkingLabel() {
currentColor=0;
//the two Backgrounds between wich is switched
BackgroundColor[0] = Color(255,0,0); //red
BackgroundColor[1] = Color(255,255,255); //white
SetTimeCallback(1000,callback(this,&BlinkingLabel::blink)); //start blinking every second
};
void BlinkingLabel::Paint(Draw& w) {
Size sz = GetSize();
if(!IsTransparent())
w.DrawRect(0,0,sz.cx,sz.cy,BackgroundColor[currentColor]);
// w.DrawRect(0,0,sz.cx,sz.cy,!IsShowEnabled(),false,false,VisibleAccessKeys()); // --- problem---
};
void BlinkingLabel::blink() {
currentColor=1 & ++currentColor; //toggle between 0 and 1
Refresh();
SetTimeCallback(1000,callback(this,&BlinkingLabel::blink)); //continue blinking every second
};
GUI_APP_MAIN
{ TopWindow w;
BlinkingLabel bl;
w.Add(bl);
bl.SetText("my background is switching every second between red and white!");
bl.LeftPosZ(55, 500).TopPosZ(51, 19);
bl.Transparent(false); //so we arent transparent and our background will be seen
w.Run();}

Thanks Luigi,
You are right, that line was wrong!
If you change that line like seen here, the label will also be drawn.
it should be:
#include <CtrlLib/CtrlLib.h>
class BlinkingLabel : public Label {
private:
int currentColor;
Color BackgroundColor[2];
public:
BlinkingLabel();
void blink();
virtual void Paint(Draw& w);
};
BlinkingLabel::BlinkingLabel() {
currentColor=0;
//the two Backgrounds between wich is switched
BackgroundColor[0] = Color(255,0,0); //red
BackgroundColor[1] = Color(255,255,255); //white
SetTimeCallback(1000,callback(this,&BlinkingLabel::blink)); //start blinking every second
};
void BlinkingLabel::Paint(Draw& w) {
Size sz = GetSize();
if(!IsTransparent())
w.DrawRect(0,0,sz.cx,sz.cy,BackgroundColor[currentColor]);
PaintLabel(w,0,0,sz.cx,sz.cy, !IsShowEnabled(), false,false,VisibleAccessKeys());
};
void BlinkingLabel::blink() {
currentColor=1 & ++currentColor; //toggle between 0 and 1
Refresh();
SetTimeCallback(1000,callback(this,&BlinkingLabel::blink)); //continue blinking every second
};
GUI_APP_MAIN
{ TopWindow w;
BlinkingLabel bl;
w.Add(bl);
bl.SetText("my background is switching every second between red and white!");
bl.LeftPosZ(55, 500).TopPosZ(51, 19);
bl.Transparent(false); //so we arent transparent and our background will be seen
w.Run();}
