on your form. To accomplish this, create an instance of the
TOpenDialog class and then call its Execute() method:
TOpenDialog openDlg = new TOpenDialog(this);
if (openDlg->Execute()) {
// do something here
}
delete openDlg;
If necessary, you can set any of the OpenDialog component’s properties
before calling Execute().
The Color Dialog Box
The Color dialog box allows the user to choose a color. When the OK button is clicked, the
Color property will contain the color information. (Refer to Figure 8.1, which shows the
Color dialog box.) The Color dialog box, like the file dialog boxes, has no events to respond to.
The Font Dialog Box
The Font dialog box allows the user to choose a font from the list of fonts available on his
or her system. Through the Device property, you can choose whether you want screen fonts,
printer fonts, or both types of fonts to be displayed. You can limit the maximum and
minimum font sizes that the user can select by modifying the MaxFontSize and MinFontSize
properties. As with the File dialog boxes, the Options property contains a wide variety of
options you can use to control how the Font dialog box functions.
If the user clicks OK, the Font property will contain all the information you need to
implement the new font. Figure 8.10 shows the Font dialog box in the default configuration.
