Hi all,
I'm trying to create several Fl_Output derived controls on demand and put them
by columns into a Fl_Double_Window. The width of each Fl_Output shall go with
its value, e.g. for a value "A" width should be 10 and for a value
"MyTestValue" it should be 110.
The measurement of values is done in the draw() method.
That works fine except for the top one: its width always is minimum.
Can someone help me?
Thanks in advance

Here goes my code:
#include <FL/Fl.H>
#include <FL/Fl_Double_Window.H>
#include <FL/fl_draw.H>
class Display : public Fl_Output {
public:
Display( int x, int y, int w, int h, const char *lbl ) :
Fl_Output(x,y,w,h,lbl)
{
textsize( 11 );
}
protected:
void draw() {
int wi, he;
fl_measure( this->value(), wi, he, 0 );
resize( x(), y(), wi + 6, h() );
Fl_Output::draw();
}
};
//=====================================================
class TestDisplay : public Fl_Group {
public:
TestDisplay( int x, int y, int w, int h ) : Fl_Group( x, y, w, h ) {
}
void setData( vector<string> &labels, vector<string> &values ) {
for( int i = 0, imax = labels.size(); i < imax; i++ ) {
fprintf( stderr, "label: %s\n", labels.at( i ).c_str()
);
Display *pDy = new Display( 150, y() + 3 + i * 30, 150,
25, labels.at( i ).c_str() );
pDy->value( values.at( i ).c_str() );
add( pDy );
}
}
};
//====================================================
int main() {
Fl_Double_Window *pWin = new Fl_Double_Window( 100, 100, 300, 300,
"TestDisplay" );
TestDisplay *pDisp = new TestDisplay( 0, 0, 300, 300 );
pWin->end();
pWin->show();
vector<string> labels, values;
labels.push_back( "Label 1: " );
labels.push_back( "Label 2: " );
labels.push_back( "Label 3: " );
values.push_back( "Val 1: " );
values.push_back( "TestValue 2: " );
values.push_back( "Value 3: " );
pDisp->setData( labels, values );
return Fl::run();
}
