Method for changing the size of the content displayed on display and electronic device thereof

A method of operating an electronic device, the method comprising:

• displaying web content on a touch screen display of the electronic device through a display region set in a first object, wherein the web content is rendered in a second object;
• receiving a touch input for zooming in to or zooming out of the web content with a first magnification;
• when receiving the touch input, extending a size of the second object to a size of a virtual region to restrict occurrence of a scroll of the second object, based on setting of a third object, wherein the size of the virtual region is a maximum size supported in the second object and is irrespective of the first magnification of the touch input;
• zooming in to or zooming out of the web content with the first magnification in the second object having the size of the virtual region;
• updating the display region set in the first object based on size information of the zoomed web content extracted from the second object and provided from the third object;
• identifying whether the touch input is released from the touch screen display;
• and
• in response to the touch input being released from the touch screen display, re-setting the size of the second object having the size of the virtual region in accordance with the size information of the zoomed web content based on setting of the third object,
• wherein the first object is created through a first view class, the second object is created through a second view class, and the third object is created through a third view class, and
• wherein the first object and the second object are scrollable and the third object is not scrollable.

An electronic device comprising:

• a touch screen display;
• a memory;
• and
• at least one processor coupled to the memory,
• wherein the memory is configured to store a first object created through a first view class, a second object created through a second view class, and a third object created through a third view class, wherein the first object and the second object are scrollable and the third object is not scrollable, and
• wherein the memory is further configured to store instructions that, when executed, cause the at least one processor to:
• display content on the touch screen display through a display region set in the first object, wherein the content is rendered in the second object,
• receive a touch input for changing a size of the content with a first magnification,
• when receiving the touch input, extend a size of the second object to a size of a virtual region to restrict occurrence of a scroll of the second object, based on setting of the third object, wherein the size of the virtual region is a maximum size supported in the second object and is irrespective of the first magnification of the touch input,
• change the size of the content with the first magnification in the second object having the size of the virtual region,
• update the display region set in the first object based on changed size information of the content extracted from the second object and provided from the third object,
• identify whether the touch input is released from the touch screen display, and
• in response to the touch input being released from the touch screen display, re-set the size of the second object having the size of the virtual region in accordance with the changed size information of the content based on setting of the third object.
