problem about renderText

[tyzhang3]

hi:

I used two qglwidget in my mainwindow. And I invoked renderText in both of the qglwidget. But in one of the qglwidget, I just cannot change the color of text. Could you please help me?

Code like below:

void VARDrawer::DrawLabel()
{
	setting->ValidateLabels();
	glLineWidth(1.2f);
	glColor4f(1.0f,0.0f,0.0f,1.0f);:confused:Do not work here
 
	map<int,TextureSetting*>::iterator mi;
	for (mi = setting->varMap.begin();
		mi != setting->varMap.end() ; mi++)
	{
		TextureSetting* texSetting = mi->second;
		if (texSetting->isDrawLabel)
		{
 
			QString label(texSetting->srcDim->GetDimensionName().c_str());
			Vec3 pos = Vec3(texSetting->blockPos.X,
				texSetting->blockPos.Y+texSetting->VisSize.height+0.02f,
				0.0f);
 
			renderText(pos.X, pos.Y,0.0f, 
				texSetting->srcDim->GetDimensionName().c_str());
 
		}
	}
}
void PareCoordDrawer::DrawAxisLabel(void)
{
	setting->ValidateAxisLabel(dataSet);
	glLineWidth(1.2f);
	qglColor(Qt::red);
	QVector<float>::iterator qli;
	QList<string>::iterator qsli;
	for (qli = setting->axisPos.begin(), qsli = setting->labelList.begin();
		qli != setting->axisPos.end(); qli++, qsli++)
	{
		float pos = *qli;
		string dimName = *qsli;
		renderText(pos, 1.05f, 0.0f, dimName.c_str());:o Every thing just fine here
	}
}

void VARDrawer::DrawLabel()
{
	setting->ValidateLabels();
	glLineWidth(1.2f);
	glColor4f(1.0f,0.0f,0.0f,1.0f);:confused:Do not work here
	
	map<int,TextureSetting*>::iterator mi;
	for (mi = setting->varMap.begin();
		mi != setting->varMap.end() ; mi++)
	{
		TextureSetting* texSetting = mi->second;
		if (texSetting->isDrawLabel)
		{
			
			QString label(texSetting->srcDim->GetDimensionName().c_str());
			Vec3 pos = Vec3(texSetting->blockPos.X,
				texSetting->blockPos.Y+texSetting->VisSize.height+0.02f,
				0.0f);
			
			renderText(pos.X, pos.Y,0.0f, 
				texSetting->srcDim->GetDimensionName().c_str());
			
		}
	}
}
void PareCoordDrawer::DrawAxisLabel(void)
{
	setting->ValidateAxisLabel(dataSet);
	glLineWidth(1.2f);
	qglColor(Qt::red);
	QVector<float>::iterator qli;
	QList<string>::iterator qsli;
	for (qli = setting->axisPos.begin(), qsli = setting->labelList.begin();
		qli != setting->axisPos.end(); qli++, qsli++)
	{
		float pos = *qli;
		string dimName = *qsli;
		renderText(pos, 1.05f, 0.0f, dimName.c_str());:o Every thing just fine here
	}
}
